| 1 | Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development. | Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding | 2020 | Science China Chemistry2020，63，6： | 15 |
| 2 | Decoration of Terpyridine with Electron-Rich Unit TH DTAP: an Efficient Way to Explore Fluorescence Sensors for Recognizing Metal Ions显示文摘The electron-donating unit 2,3,4,6-tetrahydro-1,6-dithia-3a-azaphenalene (THDTAP) was introduced onto terpyridine (TPy) to give a donor-acceptor (D-A) type TPy-ligand (compound 2).Upon selective oxidation of two sulfur atoms on the THDTAP moiety of 2,the ligands 3-6 were created.The electronic structures of 2-6 were evaluated by theoretical,electrochemical,and spectroscopic investigations.The oxidation on the sulfur atoms brings significant influence on the electron-donating ability of THDTAP moiety,subsequently,leads to fine modulations on intramolecular charge-transfer (ICT) of 2-6 and the electronically excited states of the complexes of 2-6 with metal ions.Based on the optical response of 2-6 toward metal ions,the step-by-step recognition of Zn2+,Cd2+,and Ag+ ions is set up by employing 2 and 3 as combined fluorescence sensors. | Taoshan Xu Dongxu Li Chaoxian Yan Yuewei Wu Cheng-Shan Yuan Xiangfeng Shao | 2019 | Chinese Journal of Chemistry2019，37，9： | 2 |
| 3 | Molecular uniting set identified characteristic(MUSIC): a promising strategy for purely organic RTP luminogens显示文摘The room temperature phosphorescences(RTP)are of growing interest owing to their promising applications in material science and bioimaging.To date,the lumiogens showing persistent RTP effect mainly contain the noble metals which have the shortcomings such as high cost,potential toxicity.The exploration of metal free luminogens,i.e.,purely organic RTP luminogens,is thus of great importance for the community.The organic RTP materials could be created by means of cocrystals,and recently it | Xiangfeng Shao | 2018 | Science China Chemistry2018，61，8： | 1 |
| 4 | Safety and immunogenicity of a mosaic vaccine booster against Omicron and other SARS-CoV-2 variants:a randomized phase 2 trial显示文摘An ongoing randomized,double-blind,controlled phase 2 trial was conducted to evaluate the safety and immunogenicity of a mosaic-type recombinant vaccine candidate,named NVSI-06-09,as a booster dose in subjects aged 18 years and older from the United Arab Emirates(UAE),who had administered two or three doses of inactivated vaccine BBIBP-CorV at least 6 months prior to enrollment.The participants were randomly assigned with 1:1 to receive a booster dose of NVSI-06-09 or BBIBP-CorV.The primary outcomes were immunogenicity and safety against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron variant,and the exploratory outcome was cross-immunogenicity against other circulating strains.Between May 25 and 30,2022,516 adults received booster vaccination with 260 in NVSI-06-09 group and 256 in BBIBP-CorV group.Interim results showed a similar safety profile between two booster groups,with low incidence of adverse reactions of grade 1 or 2.For immunogenicity,by day 14 post-booster,the fold rises in neutralizing antibody geometric mean titers(GMTs)from baseline elicited by NVSI-06-09 were remarkably higher than those by BBIBP-CorV against the prototype strain(19.67 vs 4.47-fold),Omicron BA.1.1(42.35 vs 3.78-fold),BA.2(25.09 vs 2.91-fold),BA.4(22.42 vs 2.69-fold),and BA.5 variants(27.06 vs 4.73-fold).Similarly,the neutralizing GMTs boosted by NVSI-06-09 against Beta and Delta variants were also 6.60-fold and 7.17-fold higher than those by BBIBP-CorV.Our findings indicated that a booster dose of NVSI-06-09 was well-tolerated and elicited broad-spectrum neutralizing responses against divergent SARS-CoV-2 variants,including Omicron and its sub-lineages. | Nawal Al Kaabi Yun Kai Yang Yu Liang Ke Xu Xue Feng Zhang Yun Kang Yu Qin Jin Jun Wei Hou Jing Zhang Tian Yang Salah Hussein Mohamed Saif ElDein Ze Hua Lei Hao Zhang Shuai Shao Zhao Ming Liu Ning Liu Xiang Zheng Ji Guo Su Sen Sen Yang Xiangfeng Cong Yao Tan Wenwen Lei Xue Jun Gao Zhiwei Jiang Hui Wang Meng Li Hanadi Mekki Mekki Walid Zaher Sally Mahmoud Xue Zhang Chang Qu Dan Ying Liu Jing Zhang Mengjie Yang Islam Eltantawy Peng Xiao Fu Jie Shen Jin Juan Wu Zi Bo Han Li Fang Du Fang Tang Shi Chen Zhi Jing Ma Fan Zheng Ya Nan Hou Xin Yu Li Xin Li Zhao Nian Wang Jin Liang Yin Xiao Yan Mao Jin Zhang Liang Qu Yun Tao Zhang Xiao Ming Yang Guizhen Wu Qi Ming Li | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 0 |
| 5 | Stimuli-Responsive Polycycles Based on Hetero-Buckybowl Trithiasumanene显示文摘Stimuli-responsive molecules are highly desirable in different scenario such as smart materials,bio-imaging,and environment monitoring.Herein,a series of hetero polycycles which show optical response toward chemical stimuli are synthesized from trithiasumanene(TTS).The TTS is transformed into ortho-quinone form,which then undergoes three-component Debus-Radziszewski reaction with aldehydes and ammonia to give oxazole-fused TTS(2-6).The thiophene rings on 3-5 are selectively oxidized to thiophene-S,S-dioxides,affording 3-3O_(2)-5-3O_(2).It is found that the electronic structures of these compounds are governed by the sub-stituents on oxazole moiety and oxidation state of thiophene ring.Moreover,these hetero polycycles exhibit optical response toward different chemical stimuli.Particularly,compounds 6 and 3-3O_(2) can serve as fluorescence detectors for harmful chemicals sulfide ions(S2-/HS-)and aniline,respectively.This work indicates that TTS is a promising precursor for the creation of responsive materials. | Wenbo Wang Lijun Feng Xinqiang Hua Chengshan Yuan Xiangfeng Shao | 2021 | Chinese Journal of Chemistry2021，39，12： | 0 |
| 6 | enOsCas12f1-mediated exon skipping for Duchenne muscular dystrophy therapy in humanized mouse model显示文摘Duchenne muscular dystrophy(DMD)is a severe neuromuscular disorder caused by mutations in the dystrophin gene,which encodes the essential protein dystrophin.This genetic condition,affecting approximately 1 in 5000 male births worldwide(Birnkrant et al.,2018),is characterized by progressive muscle weakness and wasting,leading to premature death in the second or third decade of life(Farini et al.,2016).The absence of dystrophin protein causes instability in the sarcolemma,which predisposes individuals to myonecrosis and activation of inflammatory signaling cascades.Unfortunately,there is currently no effective cure for DMD,and glucocorticoid steroids are commonly used in clinical settings to delay symptom development(Merlini et al.,2003). | Ming Jin Jiajia Lin Yu Zhang Qingquan Xiao Xiangfeng Kong Xiumei Zhang Zhurui Shao Yin Wang Yuyang Yu Jinjing Li Wan-Jin Chen Guoling Li Hui Yang Ning Wang | 2024 | Journal of Genetics and Genomics2024，51，2： | 0 |

| 8 | N-Aryl diketopyrrolopyrrole derivatives towards organic optical and electronic materials显示文摘Diketopyrrolopyrrole(DPP)and related derivatives have drawn great attention due to their applications in organic optical/electronic materials.Progress in these materials is associated with developments in the syntheses of the DPP family.Chemical modification of DPP at nitrogen atom,including N-alkylation and N-arylation,is an effective strategy to improve its physical and chemical properties,such as solubility,optical and semiconducting properties.However,N-arylation of DPPs remains challenging compared to the easily accessible N-alkylation.Herein,the synthesis of N-aryl DPP derivatives and correlatedπ-expanded DPPs are summarized,and their optical/electronic properties are introduced.The future perspectives of N-aryl DPP derivatives are also discussed. | Jinqiu Meng Nan Luo Guanxin Zhang Xiangfeng Shao Zitong Liu Deqing Zhang | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
| 9 | Wide-range color-tunable afterglow emission by the modulation of triplet exciton transition processes based on buckybowl structure显示文摘Buckybowl structures as non-uniform electrostatic potential distributions of poly-cyclic aromatic materials show a unique photoelectric performance.In this work,OTC was utilized for dynamic modulation of triplet exciton transition processes.Five host molecules with different functional units were selected,thus providing dif-ferent intermolecular interactions in the host/guest systems.Therefore,the delayed emissions were regulated from 536 to 624 nm via the tuning of the triplet exciton transition processes of OTC in different hosts.Experimental data and theoretical calculations revealed that the varied triplet transition behaviors resulted from the competition between the intersystem crossing(ISC)process of OTC-monomer and the reverse intersystem crossing(RISC)process of OTC-aggregates.This work proves the superior structure of buckybowl-based luminophore for controlling triplet exciton transition processes and supplies a new perspective for persistent afterglow luminophore design. | Yongfeng Zhang Chenchen Xiong Wenbo Wang Wenbo Dai Yue Ren Junming Xia Gengchen Li Jianbing Shi Bin Tong Xiaoyan Zheng Xiangfeng Shao Zhengxu Cai Yuping Dong | 2023 | Aggregate2023，4，4： | 0 |
