Patent ID: 8354666

Claim:
An organic polymer semiconductor, represented by Formula 1 below: wherein R 1 is hydrogen, a hydroxyl group, a C 1-20 linear, branched or cyclic alkyl group, a C 1-20 alkoxyalkyl group, or a C 1-16 linear, branched or cyclic alkoxy group, R 2 and R 3 are each independently hydrogen, a hydroxyl group, a C 1-20 linear, branched or cyclic alkyl group, a C 1-20 alkoxyalkyl group, a C 1-16 linear, branched or cyclic alkoxy group, or a C 4-30 substituted or unsubstituted aryl group or heteroaryl group, D is a C 4-30 aryl group or alkylene substituted with an electron-withdrawing side-chain, including —CN, —NO 2 , —COOR, fluorine or a C 1-16 perfluoroalkyl group, and X is S, O, Se, N—H, or N—R, in which R is hydrogen or a C 1-6 linear, branched or cyclic alkyl group, a, b and c are each independently an integer of about 1 or about 2, m is an integer from about 1 to about 4, and n is an integer from about 4 to about 100.
