Synthesis and Field-Effect Transistor Properties of a Diseleno[3,2-B:2′,3′-D]silole-based Donor–acceptor Copolymer: Investigation of Chalcogen Effect

We have designed and synthesized a tricyclic diseleno[3,2-b:2′,3′-d]silole (DSS) wherein the 3,3′-position of a biselenophene is bridged by a dioctylsilyl moiety.
