| 1 | Aggregation-induced emission: a coming-of-age ceremony at the age of eighteen显示文摘Aggregation-induced emission(AIE) has drawn great attention worldwide for its unique optical phenomenon and huge potential applications. Since coined by Ben Zhong Tang et al. in 2001, AIE has been deeply investigated and widely utilized in many important areas, such as organic light-emitting diode(OLED), sensor, and bio-imaging. Herein, we highlight some important progress of AIE in these eighteen years, including the exploration of internal mechanism and potential applications. Furthermore,some other interestingly emissive behaviors, originating but distinguishing from the AIE concept, are presented. It is anticipated an overall understanding about AIE could be easily caught from this short review for scientists, no matter whether they are involved in this exciting and rising research area or not. | Jie Yang Zhenguo Chi Weihong Zhu Ben Zhong Tang Zhen Li | 2019 | Science China Chemistry2019，62，9： | 25 |
| 2 | Preparation and self-assembly of amphiphilic polymer with aggregation-induced emission characteristics显示文摘An amphiphilic polymer bearing tetraphenylethene (TPE) moiety was synthesized by convenient reactions. The polymer exhibits unique aggregation-induced emission (AIE) characteristics and can self-assemble to size-tunable particles in DMF/water mixtures. The polymer nanoparticles can be used for cell imaging, which provides a potential stable fluorescent tool to monitor the distribution of drugs and bioconjugates in living cells. | QIN AnJun ZHANG Ya HAN Ning MEI Ju SUN JingZhi FAN WeiMin TANG Ben Zhong | 2012 | Science China Chemistry2012，55，5： | 16 |
| 3 | Extracellular vesicles from human urine-derived stem cells prevent osteoporosis by transferring CTHRC1 and OPG显示文摘Osteoporosis is a debilitating bone disease affecting millions of people. Here, we used human urine-derived stem cells(USCs),which were noninvasively harvested from unlimited and easily available urine, as a 'factory' to obtain extracellular vesicles(USCEVs) and demonstrated that the systemic injection of USC-EVs effectively alleviates bone loss and maintains bone strength in osteoporotic mice by enhancing osteoblastic bone formation and suppressing osteoclastic bone resorption. More importantly, the anti-osteoporotic properties of USC-EVs are not notably disrupted by the age, gender, or health condition(with or without osteoporosis) of the USC donor. Mechanistic studies determined that collagen triple-helix repeat containing 1(CTHRC1) and osteoprotegerin(OPG) proteins are enriched in USC-EVs and required for USC-EV-induced pro-osteogenic and anti-osteoclastic effects. Our results suggest that autologous USC-EVs represent a promising novel therapeutic agent for osteoporosis by promoting osteogenesis and inhibiting osteoclastogenesis by transferring CTHRC1 and OPG. | Chun-Yuan Chen Shan-Shan Rao Yi-Juan Tan Ming-Jie Luo Xiong-Ke Hu Hao Yin Jie Huang Yin Hu Zhong-Wei Luo Zheng-Zhao Liu Zhen-Xing Wang Jia Cao Yi-Wei Liu Hong-Ming Li Yang Chen Wei Du Jiang-Hua Liu Yan Zhang Tuan-Hui Chen Hao-Ming Liu Ben Wu Tao Yue Yi-Yi Wang Kun Xia Peng-Fei Lei Si-Yuan Tang Hui Xie | 2019 | Bone Research2019，7，3： | 14 |
| 4 | Room temperature phosphorescence from natural products: Crystallization matters显示文摘Efficient room temperature phosphorescence is observed in natural compounds and polymers such as starch, cellulose, bovine serum albumin (BSA), and some other carbohydrates. Whereas being practically nonluminescent in solutions and TLC plates, they emit bright phosphorescence in the crystalline states with lifetime up to microseconds, exhibiting crystallization-induced phosphorescence (CIP) characteristics. The CIP of these natural products without any conventional chromophores offers a new platform for the exploration of conceptually novel luminogens. | GONG YongYang TAN YeQiang MEI Ju ZHANG YiRen YUAN WangZhang ZHANG YongMing SUN JingZhi TANG Ben Zhong | 2013 | Science China Chemistry2013，56，9： | 8 |
| 5 | Host–guest materials with room temperature phosphorescence:Tunable emission color and thermal printing patterns显示文摘The research of purely organic materials with long afterglow has drawn more and more attention,especially for those with stimulus‐response characteristic.So far,this kind of material is really very scarce and their performance is not good enough.In this study,we successfully developed an efficient heatingresponsive room‐temperature phosphorescence material with phosphorescence efficiency and lifetime up to 13.4%and 2.08 s through the simple host–guest doping strategy.Further on,by introducing the additional energy acceptor of fluorescein with concentration‐dependent emission to construct ternary doping systems,the afterglow color was extended from blue to yellow.Accordingly,the multicolor thermal printings have been easily realized,showing the great practical application prospects. | Yunsheng Wang Jie Yang Yanxiang Gong Manman Fang Zhen Li Ben Zhong Tang | 2020 | SmartMat2020，1，1： | 8 |
| 6 | Facile synthesis of poly(aroxycarbonyltriazole)s with aggregation-induced emission characteristics by metal-free click polymerization显示文摘Regioseletive 1,3-dipolar polycycloadditions of 4,4'-isopropylidenediphenyl dipropiolate (1) and tetraphenylethene (TPE)-containing diazides (2) are carried out in polar solvents such as DMF/toluene at a moderate temperature of 100℃ for 6 h,producing poly(aroxycarbonyltriazole)s (PACTs) P3 with high molecular weights (Mw up to 23900) and regioregularities (F1,4 up to ~90%) in high yields (up to ~99%).These metal-free click polymerizations can propagate smoothly in an open atmosphere without protection from oxygen and moisture.The obtained polymers are soluble in common organic solvents and thermally stable at temperatures up to 375℃.Thanks to their contained TPE moieties,the PACTs show aggregation-induced emission and can serve as fluorescent chemosensors for superamplified detection of explosives. | LI HongKun MEI Ju WANG Jian ZHANG Shuang ZHAO QiuLi WEI Qiang QIN AnJun SUN JingZhi TANG Ben Zhong | 2011 | Science China Chemistry2011，54，4： | 8 |
| 7 | Flame-retardant concentrated electrolyte enabling a Li F-rich solid electrolyte interface to improve cycle performance of wide-temperature lithium–sulfur batteries显示文摘Lithium–sulfur batteries have been regarded as the most promising high-energy electrochemical energy storage device owing to the high energy density, low cost and environmental friendliness. However, traditional lithium–sulfur batteries using ether-based electrolytes often suffer from severe safety risks(i.e. combustion). Herein, we demonstrated a novel kind of flame-retardant concentrated electrolyte(6.5 M lithium bis(trifluoromethylsulphonyl)imide/fluoroethylene carbonate) for highly-safe and widetemperature lithium–sulfur batteries. It was found that such concentrated electrolyte showed superior flame retardancy, high lithium-ion transference number(0.69) and steady lithium plating/stripping behavior(2.5 m Ah cm^(-2) over 3000 h). Moreover, lithium–sulfur batteries using this flame-retardant concentrated electrolyte delivered outstanding cycle performance in a wide range of temperatures(-10 °C, 25 °C and 90 °C). This superior battery performance is mainly attributed to the LiF-rich solid electrolyte interphase formed on lithium metal anode, which can effectively suppress the continuous growth of lithium dendrites. Above-mentioned fascinating characteristics would endow this flame-retardant concentrated electrolyte a very promising candidate for highly-safe and wide-temperature lithium–sulfur batteries. | Zhe Yu Jianjun Zhang Chao Wang Rongxiang Hu Xiaofan Du Ben Tang Hongtao Qu Han Wu Xin Liu Xinhong Zhou Xiaoyan Yang Guanglei Cui | 2020 | Journal of Energy Chemistry2020，29，12： | 7 |
| 8 | A Simple Approach to Bioconjugation at Diverse Levels: Metal-Free Click Reactions of Activated Alkynes with Native Groups of Biotargets without Prefunctionalization显示文摘Te efcient bioconjugation of functional groups/molecules to targeted matrix and bio-related species drives the great development of material science and biomedicine,while the dilemma of metal catalysis,uneasy premodifcation,and limited reaction efciency in traditional bioconjugation has restricted the booming development to some extent.Here,we provide a strategy for metal-free click bioconjugation at diverse levels based on activated alkynes.As a proof-of-concept,the abundant native groups including amine,thiol,and hydroxyl groups can directly react with activated alkynes without any modifcation in the absence of metal catalysis.Trough this strategy,high-efcient modifcation and potential functionalization can be achieved for natural polysaccharide,biocompatible polyethylene glycol(PEG),synthetic polymers,cell penetrating peptide,protein,fast whole-cell mapping,and even quick diferentiation and staining of Gram-positive bacteria,etc.Terefore,current metal-free click bioconjugation strategy based on activated alkynes is promising for the development of quick fuorescence labeling and functional modifcation of many targets and can be widely applied towards the fabrication of complex biomaterials and future in vivo labeling and detection. | Xianglong Hu Xueqian Zhao Benzhao He Zheng Zhao Zheng Zheng Pengfei Zhang Xiujuan Shi Ryan T.K.Kwok Jacky W.Y.Lam Anjun Qin Ben Zhong Tang | 2018 | Research2018，，1： | 7 |

| 10 | A general powder dusting method for latent fingerprint development based on AIEgens显示文摘Powder dusting method is the most practically useful approach for latent fingerprint development in the crime scene. Herein, a general powder dusting method has been explored for latent fingerprint development based on aggregation-induced emission luminogens(AIEgens). A series of tetraphenylethene(TPE) derivatives with multiple diphenylamine(DPA), namely, TPE-DPA,TPE-2 DPA and TPE-4 DPA, were selected as candidates to dope with magnetic powders and applied for latent fingerprint development. After screening, the magnetic powder 3 doped with TPE-4 DPA proves to be the best, in terms of fluorescent intensity, resolution and adhesiveness. Afterwards, the magnetic powder 3 was applied for visualization of latent fingerprint on various smooth and porous substrates, including glass, stainless steel, leaf, ceram, plastic bag, lime wall, wood and paper money.Specific details, such as island, core, termination and bifurcation, can be clearly observed for the fluorescent fingerprint images. | Zijie Qiu Bin Hao Xinggui Gu Zhaoyu Wang Ni Xie Jacky W.Y.Lam Hongxia Hao Ben Zhong Tang | 2018 | Science China Chemistry2018，61，8： | 6 |
| 11 | Crystallization-induced phosphorescence of benzils at room temperature显示文摘Efficient room temperature phosphorescence (RTP) is rarely observed in pure organic luminogens. However, we have newly observed that benzil and its derivatives are nonluminescent in solvents and thin layer chromatography (TLC) plates, but become highly phosphorescent in crystal state at room temperature, exhibiting typical crystallization-induced phosphorescence (CIP) characteristics. The CIP phenomenon is ascribed to the restriction of intramolecular rotations in crystals owing to effective intermolecular interactions. Such intermolecular interactions greatly rigidify the molecular conformation and significantly decrease the nonradiative deactivation channels of the triplet excitons, thus giving boosted phosphorescent emission at room temperature. | GONG YongYang TAN YeQiang LI Hong ZHANG YiRen YUAN WangZhang ZHANG YongMing SUN JingZhi TANG Ben Zhong | 2013 | Science China Chemistry2013，56，9： | 6 |
| 12 | Detection of the critical micelle concentration of cationic and anionic surfactants based on aggregation-induced emission property of hexaphenylsilole derivatives显示文摘We report a fluorescence 'turn-on' method to detect the critical micelle concentration (CMC) of surfactants. This method works well for both cationic and anionic surfactants. It employs an unprecedented mechanism (aggregation-induced emission, or AIE) to determine the CMC values, and the results are consistent with the data obtained by the classical techniques. In addition, this method renders the convenient detection of the CMC values. Any large and professional instruments are unnecessary, instead, a portable UV lamp and an ultrasonic generator are enough to carry out the detection in an ordinary laboratory. Considering that micelles are interesting entities and have found applications in many important fields such as emulsion polymerization, template of nanosized materials synthesis, controllable drug delivery and macromolecular self-assembling. Our experimental results may offer a facile, sensitive and promising method to detect the formation of micelles constructed by the new amphiphilic molecules and macromolecules. | TANG Li JIN JiaKe ZHANG Shuang MAO Yu SUN JingZhi YUAN WangZhang ZHAO Hui XU HaiPeng QIN AnJun TANG Ben Zhong | 2009 | Science China Chemistry2009，52，6： | 6 |
| 13 | Aggregation-induced Emission-active Hyperbranched Poly (tetrahydropyrimidine)s Synthesized from Multicomponent Tandem Polymerization显示文摘Hyperbranched polymer with highly branched three-dimensional topological structure, a large number of end groups, and multifaceted functionalities have gained much attention, while polymers with aggregation-induced emission(AIE) properties become a group of popular luminescent materials recently. The design and synthesis of AIE-active hyperbranched polymers, which combine the advantages of these two types of materials, are attractive but challenging. In this work, four hyperbranched poly(tetrahydropyrimidine)s were synthesized from the metal-free room temperature multicomponent tandem polymerization of diester group-activated internal alkyne,polyfunctional aromatic amines, and formaldehyde in methanol under the catalysis of acetic acid. Through different monomer combination and controlling the monomer loading order, hyperbranched polymers with various topological structures as well as sequences of different functional groups in the polymer backbone were obtained with high molecular weights(up to 3.0 × 10~4 g/mol) in high yields(up to 98%). The hyperbranched poly(tetrahydropyrimidine) emitted faintly in solution, while its luminescence was notably enhanced in the aggregated state, suggesting its typical aggregation-induced emission property. It is anticipated that the multicomponent polymerization may provide a synthetic platform for the construction of hyperbranched polyheterocycles with diverse structures and functionalities. | Yuzhang Huang Ping Chen Bo Wei Rongrong Hu Ben Zhong Tang | 2019 | Chinese Journal of Polymer Science2019，37，4： | 6 |
| 14 | Signaling pathways of chronic kidney diseases,implications for therapeutics显示文摘Chronic kidney disease(CKD)is a chronic renal dysfunction syndrome that is characterized by nephron loss,inflammation,myofibroblasts activation,and extracellular matrix(ECM)deposition.Lipotoxicity and oxidative stress are the driving force for the loss of nephron including tubules,glomerulus,and endothelium.NLRP3 inflammasome signaling,MAPK signaling,PI3K/Akt signaling,and RAAS signaling involves in lipotoxicity.The upregulated Nox expression and the decreased Nrf2 expression result in oxidative stress directly.The injured renal resident cells release proinflammatory cytokines and chemokines to recruit immune cells such as macrophages from bone marrow.NF-κB signaling,NLRP3 inflammasome signaling,JAK-STAT signaling,Toll-like receptor signaling,and cGAS-STING signaling are major signaling pathways that mediate inflammation in inflammatory cells including immune cells and injured renal resident cells.The inflammatory cells produce and secret a great number of profibrotic cytokines such as TGF-β1,Wnt ligands,and angiotensin II.TGF-βsignaling,Wnt signaling,RAAS signaling,and Notch signaling evoke the activation of myofibroblasts and promote the generation of ECM.The potential therapies targeted to these signaling pathways are also introduced here.In this review,we update the key signaling pathways of lipotoxicity,oxidative stress,inflammation,and myofibroblasts activation in kidneys with chronic injury,and the targeted drugs based on the latest studies.Unifying these pathways and the targeted therapies will be instrumental to advance further basic and clinical investigation in CKD. | Qian Yuan Ben Tang Chun Zhang | 2022 | Signal Transduction and Targeted Therapy2022，7，7： | 6 |
| 15 | Recent Progress in AIE-active Polymers显示文摘The demand for highly efficient solid-state luminophores is continuously growing due to their potential applications in optoelectrical devices, chemosensors, and biological applications. The discovery of luminogens with aggregation-induced emission(AIE)by Tang et al. in 2001 provides a good reponse to this demand. Among the exploited AIE luminogens, AIE-active polymers possess many advantages such as simple synthesis, convenient structrue modifications, and good processability, which offer an extensive platform for scientists and engineers. Herein, the design principles and latest synthetic advancement of AIE-active polymers are summarized, including click polymerization and multicomponent polymerization. Non-conjugated heteroatom-rich polymers were in situ generated and demonstated non-conventional clusteroluminoscence. Advanced applications including fluorescent sensors, stimuli-responsive materials,biological applications, circularly polarized luminescence, and electroluminescence are then introduced in detail. AIE-active polymers display the signal-amplification effect for sensitive and selective response to chemo/bioanalytes or stimuli and enhanced photosensitization effect for cancer theranostics. Retrospecting the expansion of this field can further strengthen our belief that AIE-active polymers are promising for conceptual innovation and technological breakthroughs in the near future. | Yu Bing Hu Jacky W.Y.Lam Ben Zhong Tang | 2019 | Chinese Journal of Polymer Science2019，37，4： | 5 |
| 16 | Biocompatible organic dots with aggregation-induced emission for in vitro and in vivo fluorescence imaging显示文摘Fluorescent probes play a key role in modern biomedical research. As compared to inorganic quantum dots (QDs) composed with heavy metal elements, organic dye-based fluorescent nanoparticles have higher biocompatibility and are richer in variety. However, traditional organic fluorophores tend to quench fluorescence upon aggregation, which is known as aggregation-caused quenching (ACQ) effect that hinders the fabrication of highly emissive fluorescent nanoparticles. In this work, we demonstrate the synthesis of organic fluorescent dots with aggregation-induced emission (AIE) in far-red/near-infrared (FA/NIR) region. A conventional ACQ-characteristic fluorescent dye, 3,4:9,10-tetracarboxylic perylene bisimide (PBI), is converted into an AIE fluorogen through attaching two tetraphenylethylene (TPE) moieties. The fluorescent dots with surface folic acid groups are fabricated from PBI derivative (DTPEPBI), showing specific targeting effect to folate receptor-overexpressed cancer cells. In vivo studies also suggest that the folic acid-functionalized AIE dots preferentially accumulate in the tumor site through enhanced permeability and retention (EPR) effect and folate receptor-mediated active targeting effect. The low cyto-toxicity, good FR/NIR contrast and excellent targeting ability in in vitro/in vivo imaging indicate that the AIE dots have great potentials in advanced bioimaging applications. | LI Kai DING Dan ZHAO QiuLi SUN JingZhi TANG Ben Zhong LIU Bin | 2013 | Science China Chemistry2013，56，9： | 5 |
| 17 | Flame-retardant quasi-solid polymer electrolyte enabling sodium metal batteries with highly safe characteristic and superior cycling stability显示文摘Con ventio nal liquid electrolytes based sodium metal batteries suffer from severe safety hazards owing to electrolyte leakage,in flammability and dendritic sodium deposit!on.Herein,we report a flame-retardant quasi-solid polymer electrolyte with poly(methyl vinyl ether-alt-maleic an hydride)(P(MVE-alt-MA))as host,bacterial cellulose(BC)as reinforceme nt,and triethyl phosphate/vinyle ne carb on ate/sodium perchlorate(TEP/VC/NaClO4)as plasticizer for highly safe sodium metal batteries.The as-obtained quasi-solid polymer electrolyte exhibits superior flame retardancy(self-extinguish within 1 s),complete non-leakage property and wide electrochemical windows(4.4 V).More importantly,Na3V2(PO4)3/Na metal batteries using such polymer electrolyte delivers superior I on g-term cycli ng stability(84.4%capacity rete ntion after 1000 cycles)which is significantly better than that(only 2%after 240 cycles)of liquid electrolyte.In addition,this flame-retardant quasi-solid polymer electrolyte provides favorable cycle performance(80.2%capacity retention after 70 cycles at 50°C and 84.8%capacity retention after 50 cycles at-10°C)for Na3V2(PO4)3/Na metal batteries.And this battery also displayed a normal charge/discharge property even at-15°C.These fascinating cycle properties are mainly ascribed to the effective pro怕ctive layers formed on Na3V2(PC>4)3 cathode and sodium metal ano de.More thorough in vestigati on elucidates that such flame-retardant quasi-solid polymer electrolyte plays a multif unctional role in the adva need sodium metal batteries:(1)being in volved in the formatio n of a favorable cathode electrolyte in terface(CEI)to inhibit the dissolutio n of van adium and maintai n the structure integrity of the Na3V2(PO4)3;(2)participati ng in building a stable solid electrolyte in terface(SEI)to suppress the growth of Na dendrites;(3)integrating flame-retardanee into polymer sodium batteries to enhance flame-resistanee,eliminate electrolyte leakage,and thus improve safety of sodium batteries.Based on these results,we further assembled Na3V2(PO4)3/MoS2 pouch cell which can withsta nd harsh conditions(be nded or cut off a corn er),confirming the obtai ned polymer electrolyte with superior non-leakage property.In all,these outstanding characteristics would endow this flame-retardant quasi-solid polymer electrolyte a very promising can didate for highly-safe sodium metal batteries. | Jinfeng Yang Min Zhang Zheng Chen Xiaofan Du Suqi Huang Ben Tang Tiantian Dong Han Wu Zhe Yu Jianjun Zhang Guanglei Cui | 2019 | Nano Research2019，12，9： | 4 |
| 18 | Mechanistic connotations of restriction of intramolecular motions(RIM)显示文摘Molecules are all in constant motions,which influence their properties. For example, in photophysics, the light emission behavior of a luminogen is determined by its electronic and nuclear motions in the excited state. Flexible molecular motions usually favor nonradiative decay along with the transformation of excited-state energy to other forms such as thermal energy. Therefore,the restriction of intramolecular motions(RIM) is commonly adopted to achieve luminescent materials with high emission brightness. | Yujie Tu Zheng Zhao Jacky W.Y.Lam Ben Zhong Tang | 2021 | National Science Review2021，8，6： | 4 |

| 20 | Thiol-yne click polymerization显示文摘The research on using thiol-ene click reaction to synthesize sulfur-containing polymers with topological structures and advanced functional properties is a hot topic. However, the application of the thiol-yne reaction in the functional polymer preparation is limited and the thiol-yne click polymerization is to be further developed. In this review, we summarized recent research efforts on using thiol-yne click polymerization to synthesize polymers with topological structures. The sulfur-containing polymers were facilely prepared by photo-and thermo-initiated, amine-mediated, and transition-metal-catalyzed thiol-yne click polymerizations. These polymers are promising to be used as drug-delivery vehicles, high refractive index optical materials, photovoltaic materials, and biomaterials etc. | YAO BiCheng SUN JingZhi QIN AnJun TANG Ben Zhong | 2013 | Chinese Science Bulletin2013，58，22： | 4 |
