A series of bulky end-capped [1]benzothieno[3,2-b]benzothiophenes (BTBTs) are developed in order to tune the packing structure via terminal substitution. A coupled theoretical and experimental study allows us to identify 2,7-di-tert-butylBTBT as a new high-performance organic semiconductor with large and well-balanced transfer integrals, as evidenced by quantum-chemical calculations. Single-crystal field-effect transistors show a remarkable average saturation mobility of 7.1 cm(2) V(-1) s(-1) .
为了通过末端取代来调整堆积结构，开发了一系列大型端封[1]苯并噻吩[3,2-b]苯并噻吩（BTBTs）。通过理论和实验的耦合研究，我们确定 2,7-二叔丁基 BTBT 是一种新的高性能有机半导体，具有较大且平衡的转移积分，这一点可通过量子化学计算得到证明。单晶场效应晶体管显示出显著的平均饱和迁移率为 7.1cm(2)V(-1)s(-1)。
