Claim:
1. An electronic device comprising a semiconducting layer, the semiconducting layer comprising: an amorphous polymer binder; and a crystalline small molecule semiconductor having an average crystal size which is at least two times smaller than that of the small molecule semiconductor in a semiconducting layer that has been thermally treated at a temperature greater than the melting temperature of the small molecule semiconductor; wherein the semiconducting layer has a field-effect mobility of at least 0.2 cm2/V·sec, and wherein the small molecule semiconductor has the structure of Formula (I): wherein each R m and n are the number of R1 sidechains on their respective phenyl or naphthyl ring, and are independently an integer from 0 to 6; X is selected from the group consisting of O, S, and Se; and a, b, and c are independently 0 or 1, provided that at least one of a, b and c is 1.
