Abstract
Disclosed herein is a composition comprising a regioregular oligothiophene, a regioregular poly[2,5-bis(3-alkylthiophen-2-yl)thieno(3,2-b)thiophene] and/or a benzothiophene; where the regioregular oligothiophene, the regioregular poly[2,5-bis(3-alkylthiophen-2-yl)thieno(3,2-b)thiophene] and the benzothiophene each have a number average molecular weight of less than or equal to 475 grams per mole; where the composition is melted and then annealed at a temperature between a melting point and a glass transition temperature of the composition; the composition having a charge mobility that is greater than a comparative composition that is either not annealed or annealed at the same temperature between the melting point and the glass transition temperature but without being subjected to prior melting.
