Three porphyrins, meso-5,10,15, 20-tetrakis(2-thienyl) porphyrin and meso-5, 10,15,2Q-tetrakis(4-bromo-2-thienyl)porphyrin and meso-5, 10,15)20-tetrakis(3-methyl-2-thienyl)poiphyrin, were synthesized in 35% ~ 39 % yields in a mixture solvent [ propionic acid: acetic acid: nitrobenzene = 2:2(or3) = l] at 130 ~ 140 t for 40 ~ 60 min from condensation of substitutional-2-thienyl aldehyde with pyrrole. 15 complexes of title porphyrins with Fe~(2+) , Fe~(3+) , Co~(2+) , Ni~ (2+) , Mn~(2+) were synthesized by the method of solid state synthesis at 40 °C in 81% ~ 87% yields. They were characterized by elemental analysis, UV-vis, ffi, 1H NMR, HRMS spectra. Their thermal decomposition characters were determined by TG-DTA, Showing 4 molecules of water is contained. The complexes decompose in two steps at 349 ~ 621 °C . Their magnetisms were characterized by EPR, all of tide porphyrins and their complexes have paramagnetism.
