Abstract
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.
