Synthesis of chalcone-containing zinc and cobalt metallophthalocyanines; investigation of their photochemical, DPPH radical scavenging and metal chelating characters

Abstract

In this study, two new phthalocyanines (M = Zn and Co) were synthesized using the (E)-4-(4-(3-(4-(benzyloxy)phenyl)acryloyl)phenoxy)phthalonitrile (3) as ligand prepared from the chemical reaction of 4-nitrophthalonitrile with (E)-3-(4-(benzyloxy)phenyl)-1-(4-hydroxyphenyl)prop-2-en-1-one (2). All compounds were characterized using by 1H-NMR, 13C-NMR, UV-Vis, FT-IR, and MALDI-TOF mass spectra. Singlet oxygen quantum yields of the synthesized compounds, aggregates in different solutions, metal chelating and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging properties were reported.
