Small-molecule organic micro/nanocrystals (OMNCs) have unique electronic and optical properties like flexibility, versatility, and tenability, which can complement or rival their inorganic semiconductor nanocrystals. They could lead to new-generation low-cost flexible, stretchable and wearable electronic and optoelectronic devices. However, the scale-up of OMNCs for technological applications is difficult as their growth orientation and location are usually stochastic in nature. The alignment and patterning of OMNCs are prerequisite for their device applications in practice. This talk will introduce recent advances in the large-area alignment and patterning of ordered OMNCs for highperformance optoelectronic and photosynaptic devices. A highly efficient yet simple method that combines surface micro/nano-structured templates and conventional organic coating techniques, such as spin-coating, dip-coating, and blade-coating, was developed to produce organic micro/nanowire arrays at designated locations. This strategy enables wafer-scale fabrication of organic nanowire arrays with ultrahigh accuracy, reliability, and flexibility. It will also demonstrate a new type of organic photosynaptic devices based on OMNCs, which opens up opportunities for future high-performance, low-cost organic electronic and optoelectronic devices.


Prof Jiansheng Jie received his PhD degree in physics from University of Science and Technology of China (USTC) in 2004. He then worked as a postdoctoral fellow at City University of Hong Kong. After that, he joined Hefei University of Technology at 2006 as a professor. In 2010, he joined Institute of Functional Nano & Soft Materials (FUNSOM), Soochow University. His research focuses on assembly and patterning of organic micro/nanocrystals for electronic and optoelectronic devices, including organic field-effect transistors (OFETs), light-emitting diodes (LEDs) and photodetectors. He is the author or co-author of over 190 research articles in peer-reviewed journals such as Nat. Commun., Adv. Mater., Nano Lett., ACS Nano, and Adv. Funct. Mater. with a paper H-index factor of 47. These works have received over 7400 citations. He is awarded an Excellent Young Scientists Fund of National Natural Science Foundation of China (NSFC) and New Century Excellent Talents in China.
