具有不同晶体多晶型物的选择性生长的噻吩并苯衍生物的第一个实例简单地通过溶液相自组装实现。与片状a相晶体相比，基于微带状β相晶体的有机场效应晶体管（OFFET）的空穴迁移率高达18.9 cm（2）V-1 s（-1），是在环境条件下测量的p型有机半导体的最高值之一。
The first example for thienoacene derivatives with selective growth of different crystal polymorphs is simply achieved by solution-phase self-assembly. Compared with platelet-shaped a-phase crystals, organic field-effect transistors (OFETs) based on microribbon-shaped beta-phase crystals show a hole mobility up to 18.9 cm(2) V-1 s(-1), which is one of the highest values for p-type organic semiconductors measured under ambient conditions.
