Facile Synthesis of a Carboxyl-functionalized Zinc Phthalocyanine

Abstract

A facile way for synthesis of tetra-β-carboxy-methyleneaminophthalocyanine zinc is given as an example to show the feasibility for preparation of zinc phthalocyanines including carboxy groups by a novel route, namely derivation from tetra-β-aminophthalocyanine zinc via Schiff-base reaction occurred between amino group and carbonyl group of 2-oxoacetic acid.

Keywords:
