The synthesis and characterization of novel unsymmetrical azaphthalocyanines containing one carboxylic group

Abstract

Unsymmetrical zinc and magnesium complexes of azaphthalocyanines with one carboxylic group were synthesized and characterized; zinc complex showed good photodynamic properties indicating that it may be suitable as a third generation photosensitizer
