Single crystal ribbons and transistors of a solution processed sickle-like fused-ring thienoacene

Abstract

A fused-ring thienoacene with sickle-like molecular shape was synthesized and examined in self-assembly and in transistors for the first time. Different from the linear fused-ring thienoacenes with herringbone packing motif, the sickle-like thienoacene exhibits a π–π molecular packing motif and could self-assemble into one-dimensional single crystalline ribbons efficiently. Moreover, the compound demonstrates not only excellent solubility in common organic solvents, but also high mobility and stability in transistors, indicating the great application prospect of the compound in organic electronics.
