卟啉类化合物具有优良的光物理性质，是一种具有高度敏感性和选择性的荧光探针。将含有酯基和羟基的卟啉分别用于水中痕量C u2＋及Z n2＋的检测，通过不同体系下荧光信号的强度变化对重金属离子进行识别。研究结果表明，酯基卟啉和羟基卟啉都能对C u2＋及Z n2＋的浓度变化做出线性响应，酯基卟啉为荧光猝灭型探针，而羟基卟啉为荧光增强型探针，酯基卟啉对铜离子的选择性高于羟基卟啉。

Porphyrin compounds with excellent photophysical properties ,is a highly sensitive and selective fluorescent probes .The porphyrins that contain the ester group or hydroxyl group are used to determine trace concentration of Cu2+ and Zn2+ in water ,thus the metal i-ons can be identified through the intensity variations of fluorescence signal in different condi-tions .The results indicated that the ester porphyrin is fluorescence quenching probe while the hydroxy porphyrin is fluorescence enhancement probe ,and also show that although both the ester porphyrins and hydroxy porphyrins can show linear response to the changes in the con-centration of Cu2+ and Zn2+ ,the ester porphyrin selectivity for copper ions is higher than that of hydroxyl-porphyrin .
