Abstract:
1. A conducting polymer film composition useful for an organic opto-electronic device, comprising a conducting polymer and a solvent, wherein the composition comprises a graft copolymer of a self-doped conducting polymer represented by Formula 2 below: wherein A is selected from the group consisting of substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C1-C30 heteroalkyl, substituted or unsubstituted C1-C30 alkoxy, substituted or unsubstituted C1-C30 heteroalkoxy, substituted or unsubstituted C6-C30 aryl, substituted or unsubstituted C6-C30 arylalkyl, substituted or unsubstituted C6-C30 aryloxy, substituted or unsubstituted C2-C30 heteroaryl, substituted or unsubstituted C2-C30 heteroarylalkyl, substituted or unsubstituted C2-C30 heteroaryloxy, substituted or unsubstituted C5-C20 cycloalkyl, substituted or unsubstituted C2-C30 heterocycloalkyl, substituted or unsubstituted C1-C30 alkyl ester, substituted or unsubstituted C1-C30 heteroalkyl ester, substituted or unsubstituted C6-C30 aryl ester, and substituted or unsubstituted C2-C30 heteroaryl ester; B represents an ionic group or an ionic group-containing group, wherein the ionic group is a conjugate of an anion and a cation; C is selected from the group consisting of —O—, —S—, —NH—, substituted or unsubstituted C1-C30 alkylene, substituted or unsubstituted C1-C30 heteroalkylene, substituted or unsubstituted C6-C30 arylene, substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C1-C30 heteroalkyl, substituted or unsubstituted C1-C30 alkoxy, substituted or unsubstituted C1-C30 heteroalkoxy, substituted or unsubstituted C6-C30 aryl, substituted or unsubstituted C6-C30 arylalkyl, substituted or unsubstituted C6-C30 aryloxy, substituted or unsubstituted C6-C30 arylamine, substituted or unsubstituted C6-C30 pyrrole, substituted or unsubstituted C6-C30 thiophene, substituted or unsubstituted C2-C30 heteroaryl, substituted or unsubstituted C2-C30 heteroarylalkyl, substituted or unsubstituted C2-C30 heteroaryloxy, substituted or unsubstituted C5-C20 cycloalkyl, substituted or unsubstituted C2-C30 heterocycloalkyl, substituted or unsubstituted C1-C30 alkyl ester, substituted or unsubstituted C1-C30 heteroalkyl ester, substituted or unsubstituted C6-C30 aryl ester, and substituted or unsubstituted C2-C30 heteroaryl ester; D is pyrrole or thiophene represented by Formula 4 below and having substituents other than hydrogen at positions 3 and 4: wherein X is NH, N to which a C1-C20 alkyl or C6-C20 aryl substituent is attached, or a heteroatom, and R m, n and a represent mole fractions of the respective monomers, and m is greater than 0 and equal to or smaller than about 10,000,000, n is equal to or greater than 0 and smaller than about 10,000,000, a/n is greater than 0 and smaller than about 1, and a is an integer from 3 to 100.
