Synthesis and Properties of Polyaniline Attached to Cu-Phthalocyanine Functional Group in Side Chain

Abstract

Abstract: Using Cu-phthalocyanine, chlorosulfonic acid and sulfone chloride as raw materials, Cu-phthalocyanine sulfonic acid chloride was synthesized. The polyaniline containing Cu-phthalocyanine functional group in side chain (PAnCuPc) was synthesized by using Cu-phthalocyanine sulfonic acid chloride and intrinsic polyaniline. The designed chemical structure of PAnCuPc and its intermediate product can be proved by means of the elementary analysis, IR and UV-Vis. PAnCuPc is soluble in aprotic solvents such as NMP, DMF, DMAc and DMSO. It is even soluble in common solvents with a low boiling point such as THFand chloroform. In comparison with the intrinsic polyaniline, the absorption peaks of PAnCuPc shift to a low frequency direction in IRspectrum. The absorption of PAnCuPc is very intense in the range of visible light and near-infrared through UV-Vis spectrum. It can be seen from transition electron microscopy and X-ray diffraction that the crystallinity of PAnCuPc is obviously improved.

Key words: Cu-phthalocyanine sulfonic acid chloride, Polyaniline, Polyaniline attached to Cu-phthalocya-nine functional group in side chain
