摘      要：Organic single crystals(OSCs)have received increasing interest in the last decades for their potential applications in flexible *** there are various subtractive manufacturing methods of organic electronics,the subtractive manufacturing of OSCs is still a challenge,since OSCs are assembled via weak van-der-Waals interactions which are vulnerable and cannot afford damages and suffer the degradation of performances after the ***,we develop an epitaxial etching strategy which clips the OSCs and keeps high-quality crystalline nature of the resulting *** a result,high-quality organic micro-ribbon arrays are fabricated which maintains 89%charge mobility in average compared with original OSCs,showing great potential of this subtractive manufacturing method in future organic electronics.
