This research involves the synthesis of metal complexes of tetraalkylphenylporphyrin for using as soft materials. Tetraalkylphenylporphyrin derivatives were successfully synthesized in one step. The condensation of pyrrole and 4-n-butylbenzaldehyde or 4-n-octyloxybenzaldehydye were carried out giving the tetrabutylphenylporphyrin (35%) and tetraoctylphenylporphyrin (33%). The zinc and iron complexes with tetraalkylphenylporphyrins were formed by using Zn(OAc)2 or FeCl₂. All products were characterized by ¹H-NMR, mass spectroscopy and UV-Vis spectrocopy. The complexation of 4,4'-azopyridine by metal-tetraalkylphenylporphyrins was studied by UV-Vis spectrocopy. The results show that the absorbance of mixture was the combination between the absorbance of 4,4'-azopyridine and metal-tetraalkylphenylporphyrin. These suggest that the 4,4'-azopyridine-metal-tetraalkylphenylporphyrin couldn’t form.
