Abstract: On the basis of the spectroscopies such as UVabsorption spectroscopy, fluorescence spectroscopy and time-resolved fluorescence spectroscopy, the photophysical properties of o-Cl, m-Cl and p-Cl substituted zinc(Ⅱ) tetraphenylporphyrin-tyrosine have been determined.It was found that the position of the chlorine atom has a great effect on the photophysical behavior of zinc(Ⅱ) tetraphenylporphyrin-tyrosine.Comparing to the m-Cl and p-Cl substituted compounds, abnormally high fluorescence quantum yield and longer fluorescence lifetime were observed in the o-Cl substituted compound and those may be ascribed to the steric effect.

Key words: Zinc(Ⅱ) porphyrin-tyrosine, Position of the substituted group, Spectroscopic properties
