Abstract:
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 cm wherein the crystalline small molecule semiconductor has the structure of Formula (II): wherein R2 and R3 are independently selected from alkenyl, substituted alkenyl, alkenyl, substituted alkenyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, alkoxy, alkylthio, trialkylsilyl, ketonyl, cyano, and halogen.
