| 1 | Vertical‐organic‐nanocrystal‐arrays for crossbar memristors with tuning switching dynamics toward neuromorphic computing显示文摘Memristors proposed by Leon Chua provide a new type of memory device for novel neuromorphic computing applications.However,the approaching of distinct multi‐intermediate states for tunable switching dynamics,the con-trolling of conducting filaments(CFs)toward high device repeatability and reproducibility,and the ability for large‐scale preparation devices,remain full of challenges.Here,we show that vertical‐organic‐nanocrystal‐arrays(VONAs)could make a way toward the challenges.The perfect one‐dimensional structure of the VONAs could confine the CFs accurately with fine‐tune resistance states in a broad range of 103 ratios.The availability of large‐area VONAs makes the fabrication of large‐area crossbar memristor arrays facilely,and the analog switching characteristic of the memristors is to effectively imitate different kinds of synaptic plasticity,indicating their great potential in future applications. | Fangxu Yang Lingjie Sun Qingxi Duan Huanli Dong Zhaokun Jing Yuchao Yang Rongjin Li Xiaotao Zhang Wenping Hu Leon Chua | 2021 | SmartMat2021，2，1： | 5 |

| 4 | High performance organic transistors and phototransistors based on diketopyrrolopyrrole-quaterthiophene copolymer thin films fabricated via low-concentration solution processing显示文摘Conjugated polymers have received considerable attentions over the past years due to their large-area potential applications via low-cost solution processing.Improving crystallinity of conjugated polymer molecules in solution-processed thin films is crucial for their efficient charge transport and thus high performance optoelectronic devices.Herein,with diketopyrrolopyrrole-quaterthiophene(PDQT)copolymer as an example,it is found that by simply reducing the solution concentration for spincoating meanwhile with the assistance of post-annealing,significantly enhanced film crystallinity with formation of typical single crystalline domains is obtained,which benefits from the enough space for better molecular assembly especially at the semiconductor/dielectric interface.High performance polymer transistors and phototransistors were finally constructed based on the optimal lowconcentration(2 mg/mL)spin-coated PDQT films(12 nm),which giving a high charge carrier mobility of 2.28 cm^2V^(-1)s^(-1)and a photoresponse on/off ratio of 2.1×10~7at V_G=0 V under white light irradiation of6 mW/cm^2.The results suggest that the bright future of PDQT crystalline films for large-area flexible integrated optoelectronic devices and the application of effective low-concentration processing approach in solution-processed organic electronics with reduced material waste. | Pengcheng Gu Mengxiao Hu Shang Ding Guangyao Zhao Yifan Yao Feng Liu Xiaotao Zhang Huanli Dong Xiangke Wang Wenping Hu | 2018 | Chinese Chemical Letters2018，29，11： | 2 |
| 5 | Comparable charge transport property based on S…S interactions with that of π-π stacking in a bis-fused tetrathiafulvalene compound显示文摘Compact molecular packing with short π-π stacking and large π-overlap in organic semiconductors is desirable for efficient charge transport and high carrier mobility.Thus charge transport anisotropy along different directions is commonly observed in organic semiconductors.Interestingly,in this article,we found that comparable charge transport property were achieved based on the single crystals of a bis-fused tetrathiafulvalene derivative(EM-TTP) compound along two interaction directions,that is,the multiple strong S…S intermolecular interactions and the π-π stacking direction,with the measured electrical conductivity and hole mobility of 0.4 S cm^(-1),0.94 cm^2 V^(-1) s^(-1) and 0.2 S cm^(-1),0.65 cm2 V^(-1) s^(-1),respectively.This finding provides us a new molecular design concept for developing novel organic semiconductors with isotropic charge transport property through the synergistic effect of multiple intermolecular interactions(such as S…S interactions) and π-π stacking. | Ke Zhou Hongfeng Chen Huanli Dong Qi Fang Wenping Hu | 2017 | Science China Chemistry2017，60，4： | 1 |
| 6 | Unveiling the role of Fe_(3)O_(4)in polymer spin valve near Verwey transition显示文摘The spinterface formed between ferromagnetic(FM)electrode and organic materials is vital for performance optimization in organic spin valve(OSV).Half-metallic Fe_(3)O_(4)with drastic change in structure,conductivity and magnetic property near Verwey transition can serve as an intrinsic spinterface regulator.However,such modulating effect of Fe_(3)O_(4)in OSV has not been comprehensively investigated,especially below the Verwey transition temperature(Tv).Here,we highlight the important role of Fe_(3)O_(4)electrode in reliable-working and controllable Fe_(3)O_(4)/P3HT/Co polymer spin valves by investigating the magnetoresistance(MR)above and below 7V.In order to distinguish between different contributions to charge transport and related MR responses,the systematic electronic and magnetic characterizations were carried out in full temperature range.Particularly,the first-order metal-insulator transition in Fe_(3)O_(4)has a dramatic effect on the MR enhancement of polymer spin valves at 7V.Moreover,both the conducting mode transformation and MR line shape modulation could be accomplished across 7V.This research renders unique scenario to multimodal storage by external thermodynamic parameters,and further reveals the importance of spin-dependent interfacial modification in polymer spin valves. | Shuaishuai Ding Yuan Tian Xiang Liu Ye Zou Huanli Dong Wenbo Mi Wenping Hu | 2021 | Nano Research2021，14，1： | 1 |
| 7 | Well-balanced ambipolar diketopyrrolopyrrole-based copolymers for OFETs,inverters and frequency doublers显示文摘Conjugated polymers with well-balanced ambipolar charge transport is essential for organic circuits at low cost and large area with simplified fabrication techniques.Aiming at this point,herein,a novel asymmetric thiophene/pyridine-flanked diketopyrrolopyrrole-based copolymer(PPyTDPP-2FBT)is designed and synthesized.Due to the effect of incorporating F atoms on molecular energy alignment and conjugation conformation,the PPyTDPP-2FBT copolymer exhibits typical V-shaped ambipolar field-effect transfer characteristics with well-balanced hole and electron mobilities of 0.64 and 0.46 cm^(2)V^(−1)s^(−1),respectively.Furthermore,organic digital and analog circuits such as inverters and frequency doublers are successfully constructed based on solution-processed films of the PPyTDPP-2FBT copolymers which show a typical circuit operating mode with a high gain of 133 due to the well-balanced electrical properties.In addition,PPyTDPP-2FBT-based devices also demonstrate good stability and batch repeatability,suggesting their great potential applications in organic integrated electronic circuits. | Jiaxin Yang Qingqing Liu Mengxiao Hu Shang Ding Jinyu Liu Yongshuai Wang Dan Liu Haikuo Gao Wenping Hu Huanli Dong | 2021 | Science China Chemistry2021，64，8： | 1 |

| 11 | Tuning the aggregation structure and electrical property of 2.6-diphenyl-anthracene by the density of octadecyltrichlorosilane显示文摘The physical and chemical properties of organic semiconductors are closely related to their aggregation structure. Tuning of aggregation structure and electrical property is important for the application in organic electronics. In this study, a facile way to tune the aggregation structure and electrical property of 2.6-diphenyl-anthracene(DPA) is realized by using the octadecyltrichlorosilane(OTS) modification layer with different density which is fabricated by controlling reaction temperature and time.Compared with low density OTS, DPA forms larger grain size, less grain boundaries, and better molecular ordering on high density OTS surface. As a result, the charge transporting mobility of DPA film on high density OTS surface is about two orders of magnitude higher than that on low density OTS surface. The tunable aggregation structure and electrical property of DPA demonstrated here would be meaningful for the application of DPA in organic electronics. | Xi Zhang Xiaosong Chen Jie Liu Yonggang Zhen Huanli Dong Liqiang Li Wenping Hu | 2016 | Science China Chemistry2016，59，12： | 0 |

| 13 | Packing Adjustment Towards High Mobility Luminescent Conjugated Polymers显示文摘Next generation display and lighting technology calls for thinner,cheaper and more-flexible unit devices.Polymer light emitting transistor(PLET),which integrates logic function of organic field effect transistor(OFET),luminescence function of organic light emitting diode(OLED),and potential mechanical properties,is believed to be the raising star in this field.However,great challenges remain in developing the core materials of PLETs,which simultaneously require the integration of high ambipolar mobility and strong solid-state luminescence properties.Herein,high mobility luminescent thienopyrroledione-benzodiathiadiazole-fluorene-based conjugated polymer was chosen as polymer backbone,and polymers TBT-1 and TBT-2(TBT=thienopyrroledione-benzodiathiadiazole-thienopyrrole-dione)with red luminescence were obtained by direct arylation polymerization(DArP).By introducing linear alkyl side chains,the packing orientation is changed from face-on in TBT-1 thin film to edge-on in TBT-2 thin film,which is beneficial for improving the field effect performance.The average hole and electron mobility of TBT-2 are 1.1×10^(-2)and 2.0×10^(-3)cm^(2)·V^(-1)·s^(-1),respectively.This work provides new design strategy for high mobility luminescent conjugated polymers,which can be used in PLETs. | ZHANG Yihan LIU Qingqing GAO Can XIE Ziyi HU Beining DONG Huanli | 2023 | Chemical Research in Chinese Universities2023，39，5： | 0 |
| 14 | Highly Fluorescent Semiconducting Two-Dimensional Conjugated Polymer Films Achieved by Side-Chain Engineering Showing Large Exciton Diffusion Length显示文摘Semiconducting two-dimensional conjugated polymers(2DCPs)with strong fluorescence emission have great potential for various optoelectronic applications.However,it is enormously challenging to achieve this goal due to the significant compact interlayerπ-πstacking-induced quenching effect in these systems.In this work,we found that highly fluorescent semiconducting 2DCPs can be prepared through an effective side-chain engineering approach in which interlayer spacers are introduced to reduce the fluorescence quenching effect.The obtained two truxene-based 2DCP films that,along with-C6H13 and-C_(12)H_(25)alkyl side chains as interlayer spacers both demonstrate superior fluorescence properties with a high photoluminescence quantum yield of 5.6%and 14.6%,respectively.These are among the highest values currently reported for 2DCP films.Moreover,an ultralong isotropic quasi-twodimensional exciton diffusion length constrained in the plane with its highest value approaching 110 nm was revealed by the transient photoluminescence microscopy technique,suggesting that theπ-conjugated structure in these truxene-based 2DCP films has effectively been extended.This work can enable a broad exploration of highly fluorescent semiconducting 2DCP films for more deeply fundamental properties and optoelectronic device applications. | Yongshuai Wang Qing Zhang Xiao-Ze Li Zhibin Shu Yihan Zhang Can Gao Yang Li Hao Liu Chenguang Li Hong-Hua Fang Hong-Bo Sun Xiaotao Zhang Wenping Hu Huanli Dong | 2023 | CCS Chemistry2023，5，10： | 0 |

We demonstrated that this bottom-contact structure displayed an obvious improvement in the electrical characteristics relative to their pristine copper and top-contact gold electrode counterparts.
