良好取向的有机单晶半导体对于电子器件的实际应用是必不可少的。在这里，我们证明了二辛基苯并噻吩并苯并噻吩（C8-BTBT）单晶通过超声震荡辅助的溶液处理方法。实现了具有栅栏状形状的有机晶体半导体，其中棒状晶体沿着长达毫米长度的晶体骨架沿着连接在一起，这可以允许沉积的晶体联合收割机结合良好对准取向和期望沉积的特征。使用C8-BTBT单晶制造了有机场效应晶体管（OFFET），产生高达6.0 cm 2 V-1 s-1的高场效应空穴迁移率。因此，超声辅助溶解过程可以为功能材料集成到高性能器件中提供通用指南。
Well-aligned organic single-crystalline semiconductors are essential for practical applications in electronic devices. Here, we demonstrated dioctylbenzothienobenzothiophene (C8-BTBT) single crystals via an ultrasound concussion-assisted solution-processing method. Organic crystalline semiconductors with a fence-like shape were achieved, where rod-like crystals were joined together along a crystalline backbone up to millimeter length, which can allow the deposited crystals to combine the features of well-aligned orientation and desirable deposition. Organic field-effect transistors (OFETs) were fabricated using the C8-BTBT single crystals, yielding a high field-effect hole mobility up to 6.0 cm2 V−1 s−1. Therefore, the ultrasound-assisted solution process can provide a general guide for the integration of functional materials into high performance devices.
