| Abstract: In this paper the adduct reactions of electro-withdrawing substituent complexes of tetraphenyl (2-nitro) porphyrinato metal Zn, Ni, Co, Mn, Fe[abbrev. TP(2-NO2)PM] with nitrogenous bases were researched by spectroscopic titration and electro chemical method. When the reaction reached equilibrium, UV-spectrum was determined and the adduct constants were calculated.According to UV spectrum of TP(2-NO2)PM determined, we showed that the electro-withdrawing substituent in the porphyrin ring has influences on UV spectrum, adduct molecular number, the adduct constants and the oxidation reduction of the central metal and the porphyrin ring. |
