In this paper, we developed a new method to produce large-area single crystal arrays by using the organic semiconductor 9, 10-bis (phenylethynyl) anthracene (BPEA). This method involves an easy operation, is efficient, meets the demands of being low-cost and is independent of the substrate for large-area arrays fabrication. Based on these single crystal arrays, the organic field effect transistors exhibit the superior performance with the average mobility extracting from the saturation region of 0.2 cm 2  V −1 s −1  (the highest 0.47 cm 2  V −1 s −1 ) and on/off ratio exceeding 10 5 . In addition, our single crystal arrays also show a very high photoswitch performance with an on/off current ratio up to 4.1 × 10 5 , which is one of the highest values reported for organic materials. It is believed that this method provides a new way to fabricate single crystal arrays and has the potential for application to large area organic electronics.
