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 cm² V⁻¹ s⁻¹, respectively. Furthermore, the structure-property relationships of these semiconductors were also investigated by XRD and AFM.
