Abstract
A semiconducting compound with the structure: where X1 and X2 are independently S, Se, SiR1R2, O, CR3R4, C2R5R6, N, NR7, where R1 to R7 independently comprise hydrogen, straight, branched or cyclic alkyl, akenyl or alkynyl groups, alkoxy, aryl, silyl or amino; where each of Ar1 to Ar4 is optional and independently comprises, if present, an aryl or heteroaryl group; and where Y1 to Y4 independently comprise hydrogen, reactive groups, optionally substituted straight, branched or cyclic alkyl, alkoxy, akenyl, alkynyl, amido or amino groups, optionally substituted aryl or heteroaryl where at least one of Y1 to Y4 does not comprise hydrogen; and methods and devices related thereto.
Claims12
A semiconducting compound having the structure:
- where n is an integer between 2 and 10,000 such that the compound is a polymer or oligomer;
- where X1 and X2 are independently S, Se, SiR1R2, O, CR3R4, C2R5R6, N, or NR7, where R1 to R7 independently comprise hydrogen, straight, branched, or cyclic alkyl, akenyl, or alkynyl groups, alkoxy, aryl, silyl, or amino;
- where each of Ar1 to Ar4 is optional and is independently, if present, an aryl or heteroaryl group;
- and where Y1 to Y4 independently are selected from the group consisting of hydrogen, reactive or polymerizable groups, optionally substituted straight, branched, or cyclic alkyl, alkoxy, akenyl, alkynyl, amido, or amino groups, and optionally substituted aryl or heteroaryl, where at least one of Y1 to Y4 is not hydrogen.
