The crystallinity of an organic semiconductor film determines the efficiency of charge transport in electronic devices. This report presents a micro-to-nanoscale investigation on the crystal growth of fluorinated 5,11-bis(triethylgermylethynyl)anthradithiophene (diF-TEG-ADT) and its implication for the electrical behavior of organic field-effect transistors (OFETs). diF-TEG-ADT exhibits remarkable self-assembly through spin-cast preparation, with highly aligned edge-on stacking creating a fast hole-conducting channel for OFETs.
有机半导体薄膜的结晶度决定了电子器件中电荷传输的效率。本报告展示了对氟化5,11-双（三乙基锗乙炔基）蒽并二噻吩（diF-TEG-ADT）晶体生长的微观到纳米尺度研究及其对有机场效应晶体管（OFET）电学行为的影响。通过旋涂制备，diF-TEG-ADT表现出显著的自组装，高度取向的边缘堆积为OFET创造了快速空穴传导通道。
