Patent ID: 8053158

Claim:
A photosensitive composition, comprising: a N-containing conjugated electroconductive polymer; a photoacid generator; and a solvent capable of dissolving both the electroconductive polymer and the photoacid generator, wherein the electroconductive polymer includes vinylpyridine-based polymers and copolymers, wherein the photoacid generator is a non-onium salt or an onium salt, the non-onium salt selected from the group consisting of compounds corresponding to Formula I, Formula II, Formula III, and mixtures thereof, the onium salt selected from the group consisting of compounds corresponding to Formula IV, R 6 and R 7 are independently selected from the group consisting of C1-C10 straight and branched alkyl groups and C3-C10 cycloalkyl groups, R 8 is selected from the group consisting of hydrogen, halogens, C1-C5 straight and branched alkyl groups, C1-C5 alkoxy groups, and C1-C5 haloalkyl groups, and R 9 is selected from the group consisting of C1-C10 branched alkyl groups, C3-C10 cycloalkyl groups, C6-C10 alkylphenyl groups, and C1-C10 haloalkyl groups, R 10 is selected from the group consisting of hydrogen, halogens, C1-C5 straight and branched alkyl groups, and a trifluoromethyl group, and R 11 is selected from the group consisting of C1-C10 straight, branched, and cyclic alkyl groups, C6-C10 alkylphenyl groups, C1-C10 haloalkyl groups, a phenylalkyl group, C1-C5 straight and branched alkoxy groups, a phenyl group, and a tolyl group, R 24 is selected from the group consisting of C1-C6 straight and branched alkyl groups, a phenyl group, and substituted phenylalkyl groups, R 25 is selected from the group consisting of hydrogen, halogens, C1-C4 straight, branched, and cyclic alkyl groups, and X is selected from the group consisting of C1-C8 straight, branched, and cyclic alkyl sulfonates, C1-C8 perfluoroalkyl sulfonates, naphthyl sulfonate, 10-camphor sulfonate, phenyl sulfonate, tolyl sulfonate, dichlorophenyl sulfonate, trichlorophenyl sulfonate, trifluoromethylphenyl sulfonate, Cl, Br, SbF 6 , BF 4 , PF 6 , AsF 6 , and mixtures thereof, and wherein the electroconductive polymer further comprises at least one of aniline-based polymers and copolymers and pyrrole-based polymers and copolymers.
