摘要
对水溶性镧系烯土－卟啉咯合物的合成、结构及其电化学特性进行了系统研究，讨论了其稳定性，测定了络合物的稳定常数，提出并讨论了烯土卟啉络合物的电极反应机理。
We synthesized and characterized the water-soluble tetra-p-sulfonatophenylporphyrinatolanthanide, [Ln·TPPS·OH·2im]. 3H 2O.Their stability and complex constants are also studied and determined. The structural formula of the lanthanide porphyrins is proposed, too. The lanthanide atom is sitting above the porphyrin plane. The electrode reaction mechanism of the lanthanide porphyrin complex at mercury electrode in ammoniacal(pH=9.35), phosphate(pH=7.0) and acetate(pH=4.95) buffer solutions is also studied.
