| Abstract: | Meso tetramethoxyphenyl porphyrin cobalt complexes were synthesized.The interaction between meso tetramethoxyphenyl porphyrin cobalt complexes and bovine serum albumin （BSA） was observed by fluorescence spectrum.The quenching rate constant and the binding constant and the combination number was calculated according to the date：Kq=9.619×1012L·mol-1·s-1,KA=3.475×103L·mol-1,n=0.6893.The product has strong ability of quenching the fluorescence of BSA.The quenching belongs to static quenching. |
