Abstract

Graphical abstract: Highlights: A series ofBBBTs with different side chains were designed and synthesized. The mobility properties ofBBBTs film were evaluated in OFETs device. The effect of side chains on the mobility properties were investigated by XRD and AFM. Abstract: A series of novel benzo[2, 1- b :3, 4- b ']bis[1]-benzothiophene (BBBT) derivatives with different side-chains were synthesized and characterized. And their mobility properties were evaluated based on their active layers in OFETs devices. By means of simple thermal annealing, the devices based on BBBT-4 and BBBT-6 exhibited typical p-type FETs behavior with average hole mobilities of 0.28 and 0.124 cm 2 V −1 s −1, respectively. Furthermore, the structure-property relationships of these semiconductors were also investigated by XRD and AFM.
