含酯基罗丹明衍生物对金属离子的荧光传感性能研究
首发时间:2015-09-30
摘要:本文设计合成了两种含酯基的罗丹明衍生物,研究了它们在金属离子存在下的荧光发射行为,发现这两种衍生物本身没有荧光,在汞或铜离子存在下发射橙黄色荧光,进一步增加铜离子浓度可发射"异常"蓝移的绿色荧光,并对这些荧光发射现象机理进行了探讨。

Study on fluorescence sensing performance of rhodamine derivative containing ester moiety toward metal cation
Abstract:In this paper, two ester-containing rhodamine derivatives were synthesized and their fluorescence sensing properties toward metal cations were investigated. These probes showed a Hg2+-selective orangen fluorescence, whereas presented an abnormally blue-shifted green fluorescence in the presence of Cu2+. The possible reason was discussed.
Keywords: Fluorescence analysis Rhodamine Fluorescent probes Metal cations
