Unsymmetrical benzo[1,2-b:4,5-b']dithiophene and benzothiadiazole-based molecular complexes

Abstract:

A molecular complex comprising ##STR00001## wherein X1 and X2 are independently selected from the group consisting of: H, Cl, F, CN, alkyl, alkoxy, ester, ketone, amide and aryl groups; R1, R2, R1' and R2' are side chains independently selected from the group consisting of: H, Cl, F, CN, alkyl, alkoxy, alkylthio, ester, ketone and aryl groups; R3 are selected from the group consisting of alkyl group, alkoxy group, aryl groups and combinations thereof; and wherein the thiophene groups are unsymmetrical.
