Processability is excellent poly (phthalocyanine) copolymers and methods for their preparation, method for producing a polymer composition and polymeric phthalocyanine thin film using the same.

摘要

The present invention relates to the general formula (I) of the poly (phthalocyanine), poly (phthalocyanine) copolymer already selected from the group consisting of DE and poly (phthalocyanine) carboxylic acid or its ester of the general formula (2), a method of manufacturing the polymer composition, and containing them It relates to these polymer films used. Poly (phthalocyanine) copolymer of the present invention can be used in fields such as it has the availability and excellent photosensitivity and workability in an organic solvent, a color filter, an organic photosensitive drum, a recording device or optical element.; [Wherein, R ¹ and R ² are, independently to each other, a hydrogen atom, optionally substituted linear or branched C _1-20 alkyl or alkoxy group, a substitutable straight-chain or branched C _1- having 1 to 10 oxygen atoms in the chain ₂₀ alkyl or alkoxy group, or optionally substituted phenyl, or represents a phenoxy group (which may have a group 1 to 5 C _1-6 alkyl or alkoxy group as a substituent);; R ³ and R ⁴ represents the same meaning as R ^1;; X and Y are single bonds independently, O, S, CO, SO 2, C (CF 3) 2, CR 1 2, represent NH or NR ^1, or the two phenyl rings of the tetracarboxylic acid anhydride is are fused to each other without the linking groups X and Y may form a naphthyl ring, X or Y and one may form a biphenyl structure are connected with a single bond in;; p, q and r are each 0 or greater being an integer, p + q + r is an integer number of 1 or more;; W is a hydrogen atom or symbols M (where, M is a divalent metal, trivalent, or represents a tetravalent substituted metal or metal-based oxide);; The molecular weight range of the polymer of formula (I) or (II) is preferably from 3,000 to 200,000.]
