Patent ID: 8178873

Claim:
A coating composition comprising: (a) a small molecule semiconductor of Formula (I) wherein each R 1 is independently alkyl, alkoxy, thioalkyl, hydroxyalkyl, heteroalkyl, alkenyl, alkynyl, aryl, aralkyl, halo, haloalkyl, trialkylsilyl, thienyl, formyl, acyl, alkoxycarbonyl, carboxy, aminocarbonyl, aminosulfonyl, or combination thereof; each n is independently an integer equal to 0, 1, 2, or 3; and each R 2 is independently alkyl, alkoxy, alkenyl, aryl, heteroaryl, aralkyl, heteroalkyl, heteroaralkyl, or hydroxyalkyl; (b) an insulating polymer; and (c) an organic solvent, wherein the small molecule semiconductor of Formula (I) and the insulating polymer each have a solubility of at least 0.1 weight percent based on the total weight of the coating composition.
