METHOD FOR PRODUCING TRIFLUOROMETHYL PHTHALOCYANINE CONDENSED RING DIMER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a phthalocyanine dimer with a trifluoromethyl group having new functionality in which absorption wavelength is shifted to the long wavelength side by recessing its planar structure.SOLUTION: Provided is the synthesis of a phthalocyanine dimer from phthalonitrile having a trifluoromethyl group in the following formula (1).
