dc.description.abstract	A free-base tetraphenyl porphyrin (TPP) and its corresponding metalloporphyrins (MTPP) where M = Co, Fe and Sn were synthesized and characterized by UV-visible spectroscopy, FTIR and (1)Hnmr spectroscopy. Thermal studies of these porphyrins were carried out in synthetic air from room temperature to 800 degrees C using thermal analyser. The residues of MTPP after thermal treatment were qualitatively analysed, which showed the presence of corresponding metal oxides. Further, the above MTPP were subjected to thermogravimetry-evolved gas and mass spectrometry (TG-EGA-MS) analysis for the detailed information about evolved gases at their corresponding decomposition temperatures. This information may be used to predict the probable mechanism for ring opening of the macromolecular porphyrins.	en_US
