Organic semiconductor compounds and devices

摘要

A semiconducting compound comprises the structure: where X1and X2are independently S, Se, Si, R1R2, O, CR3, N, NR4, where R1to R4independently comprise hydrogen, straight, branched or cyclic alkyl, akenyl or alkynyl groups, preferably having 1 to 20 carbons, alkoxy, aryl, silyl or amino; where each of Ar1to Ar4is optional and independently comprises, if present, an aryl or heteroaryl group; and where Y1to Y4independently comprise hydrogen, reactive groups, optionally substituted straight, branched or cyclic alkyl, alkoxy, akenyl, alkynyl, amido or amino groups, preferably having 1 to 20 carbon atoms, optionally substantial aryl or heteroaryl where at least one of Y1to Y4does not comprise hydrogen. Also shown is an electronic device having an organic semiconductor portion e.g. a thin film transistor, and method of manufacturing an electronic device by applying a solution of semiconducting compound.
