Abstract：In this paper,water-soluble 5,10,15,20-tetra-(4-p-sulfophenyl)-zinc porphyrin(ZnTPPS)was as-sembled with polyvinylpyrrolidone(PVP)to form a complex by ligand interaction,and the optical stability of the complex and the ability to produce single-linear oxygen were determined by using instruments such as a UV-visible spectrophotometer and fluorescence photometer.The results show that the ZnTPPS/PVP complex has high stability,and the optical stability gradually increases with the concentration of PVP.More impor-tantly,the ZnTPPS/PVP complex can produce more single-linear state oxygen,has higher electron transfer ability,and also has a better bactericidal effect against Staphylococcus aureus.
