A novel diselenide porphyrin dimmer was synthesized from 5-(4-hydroxylphenyl)-10,15,20-triphenyl porphyrin and powder selenium.The structure of the porphyrin was confirmed by ¹H NMR,IR,UV-Vis,and HR-MS.The interaction between the porphyrin and bovine serum albumin(BSA) was investigated by means of fluorescence spectroscopy,and the binding constant K_sv was calculated to be 3.35×10⁴ L/mol.The results show that the obtained porphyrin has a powerful ability of quenching the intrinsic fluorescence of BSA.
