Characterization and purification of 1,2,4-triazole-containing phthalocyanines synthesized by microwave method and structure elucidation by spectroscopic techniques

Abstract

The complexes of peripherally tetra-substituted metal-free (8), lead(II) (9), and zinc(II) (10) phthalocyaninederivatives were synthesized for the first time in this work. The structures of these new complex compounds have beenelucidated using many spectral methods such as electronic absorption, FT-IR, 1 H NMR, 13 C NMR, elemental analysis,and mass spectra. The thermogravimetric behavior of compounds 8–10 was determined by thermogravimetric analysismethod in addition to these spectral methods.
