Synthesis and characterization of novel phthalocyanines containing four 15-membered oxadithiadiaza mixed-donor macrocycles

Abstract

Symmetrically tetrasubstituted metal-free and metal phthalocyanines (M = 2H, Cu, Ni, Co, Zn or Fe) with four 15-membered heteroatom (N, O, S)-containing donor sites attached have been synthesized and characterized by elemental analysis, IR, NMR, UV/VIS spectroscopy and thermogravimetric analysis.
