Patent ID: 8008426

Claim:
An organic semiconductor polymer, which is represented by Formula 1 below: wherein Ar is a C 2˜30 heteroaromatic ring containing one or more electron-accepting imine nitrogen atoms, one or more hydrogen atoms of the heteroaromatic ring being substituted with Rs, in which the Rs, which are same as or different from each other, are each 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, T is a group containing about 2˜about 6 fused thiophene rings, D is a C 4˜14 hetero arylene group containing a hetero atom, other than a nitrogen atom, in an aromatic ring, or a C 6˜30 arylene group, a is an integer from about 1 to about 4, x is an integer from about 2 to about 6, y is an integer from about 0 to about 4, and n is an integer from about 4 to about 200.
