ResumoThe alignment of organic single crystals with controlled placement and reasonable throughput is a practical way to realize their ultimate applications in electronics or photoelectronics, which however is still a challenging task. Here, a facile solution-processed dip-coating method is developed to construct crystalline fullerene arrays which exhibit excellent UV-light sensing performance. Our approach has realized the large-scale production of continuous C60 single-crystal arrays in a controllable manner. The morphology, surface coverage and thickness of the final samples are modulated simply by adjusting the experimental conditions such as concentration, temperature and lifting speed, implying the versatility of our method. Moreover, the as-obtained C60 single-crystal array demonstrates stable, highly sensitive, and fast photoresponse towards UV light illumination, promising for future high-performance integrated optoelectronic device.
