新型铁离子荧光探针的合成与性质研究

Synthesis and properties of the novel Fe^(3+) fluorescence probe

设计、合成了一种基于α-氨基蒽醌和8-羟基喹啉的金属离子荧光探针3。在DMF溶液中该探针本身有荧光,当加入Fe3+后,其在358nm处产生明显的荧光淬灭,而其它金属离子基本上无明显的荧光淬灭现象,该化合物是一种高选择性的Fe3+荧光探针。

A novel fluorescence probe 3has been designed and synthesized.The results showed that a significant fluorescent quenching at 358 nm was observed when Fe3+was added to the DMF solution of the compound 3which has strong fluorescence originally.The addition of other metal ions showed no obvious fluorescent quenching.Therefore,compound 3is a good Fe3+fluorescence probe with high selectivity.
