dc.description.abstract | 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. The distannylated DSS was copolymerized with a diketopyrrolopyrrole (DPP) acceptor to form a donor-acceptor copolymer PDSSDPP. The thiophene-based dithieno[3,2-b:2\',3\'-d]silole (DTS) monomer and its corresponding copolymer PDTSDPP are also prepared as references for investigation of the chalcogen effect. Compared to PDTSDPP, PDSSDPP exhibits a more red-shifted absorption spectrum, a higher-lying HOMO energy level, and closer interchain packing associated with the more polarizable Se atom to induce stronger intermolecular interactions. The selenophene-based PDSSDPP shows a mobility of 2.47 x 10(-2) cm(2) V-1 s(-1), which is nearly one order magnitude higher than the thiophene-based PDTSDPP with a mobility of 3.89 x 10(-3) cm(2) V-1 s(-1). This result suggests that the DSS unit and its polymers are promising for OFET applications. | en_US |
