摘　　要：The method of Adler was improved to prepare a series of 5,10,15,20-tetrakis(4-alkoxyphenyl)porphyrins and their complexes containing Fe3+, Mn3+, Pb2+, Co2+, Cu2+, Zn2+. Among them there were seven new compounds. All these compounds were identified through 1H NMR, MS, IR, UV and Element analysis. The correlation between the structure of compounds and their 1H NMR, MS, IR, UV spectra was discussed and their specific spectra were explained. We found nine metalloporphyrins exhibited liquid crystal behaviour through DSC and polarized-light microscope. They had one to three mesophases and certain phase transition temperature, ?H and temperature range of L.C(?T).The method of Adler was improved to prepare a series of 5,10,15,20-tetrakis (4-alkoxyphenyl)porphyrins and their complexes containing Fe3+, Mn3+, Pb2+, Co2+, Cu2+, Zn2+. Among them there were seven new compounds. All these compounds were identified through H-1 NMR, MS, IR, UV and Element analysis. The correlation between the structure of compounds and their H-1 NMR, MS, IR, UV spectra was discussed and their specific spectra were explained. We found nine metalloporphyrins exhibited liquid crystal behaviour through DSC and polarized-light microscope. They had one to three mesophases and certain phase transition temperature, DeltaH and temperature range of L.C(DeltaT).
