The equilibrium constants of the aggregation of the metal porphyrin and the equilibrium constant of the π\|π coordination with phenothoroline have been measured by using UV\|Vis titration method. The results show that the equilibrium constants decrease in the order of K \-\{CuP\}> K \-\{NiP\}> K \-\{ZnP\}. The vitro anti\|tumor activities of the dibutyltin(Ⅳ) metal porphyrinate has some relation with the ability of aggregation and coordination with ligand of the metal porphyrin.展开更多
