Abstract

Abstract The UV-vis absorption spectrum of protoporphyrin IX shows a very sharp and strong absorption maximum peak at 398 nm in acetonitrile-water mixture solution (1: 1 v/v). When divalent metal ions such as,, and ion were added to protoporphyrin IX, metal protoporphyrin IX complexes were thereby produced. Cu-protoporphyrin IX complexes have the largest formation constant () among them. The fluorescence intensity of protoporphyrin IX was ...
