Abstract

Abstract : 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 .
