Microwave-assisted synthesis, electrochemistry and spectroelectrochemistry of phthalocyanines bearing tetra terminal-alkynyl functionalities and click approach

Published in Polyhedron NULL 2016

Abstract

This work provides a successful, easy and efficient process for the preparation of both symmetrically tetra nonperipheral and peripheral terminal alkynyl substituted zinc and cobalt phthalocyanines (Pcs) and click approach. Two different routes, conventional and microwave-assisted synthesis, have been used by direct cyclotetramerization reactions. While novel cobalt Pcs were synthesized by using only conventional method, a very fast, efficient and novel method of preparation using microwaves has been also described for the synthesis of ZnPc complexes. In order to develop a novel phthalimide conjugated zinc phthalocyanine, [2,9(10),16(17),23(24)-tetrakis((1-(2-(1,3-dioxoisoindoline-2-yl)ethyl)-1H-1,2,3-triazol-4-yl)ethoxy)phthalocyaninato]zinc(II), was also synthesized via the click reaction. The precursors and the target complexes were characterized comprehensively with 1H NMR, 13C NMR, FT-IR, UV
