Abstract

Macroheterocyclic compounds, such as metal porphyrins and phthalocyanines, have unique physical and chemical properties and have potential applications in many areas such as in medicine[1]. New structures of porphyrins and phthalocyanines can form a new base for nanotechnology. The effects of peripheral functional groups or spacer ligands on the thermal stability has not been fully investigated. Some metallo- porphyrins and metallo-phthalocyanines (TPP, TPPTiCl2, TPPWCl4, PcSiCl2, PcTiCl2, and PcWCl4) have been investigated in this paper using thermal analysis (TGA/DTG), infrared spectroscopy Fourier-transformed (FT-IR), fluorescence and UV-VIS absorbtion spectra. Thermogravimetry (TG) have been used to examin the thermochemistry, to study the thermal stability and thermal decomposition of the new complexes of porphyrins and phthalocyanines. The composition of these compounds were determined from the TGA curves..
