罗丹明席夫碱荧光探针的合成及在Cu2+和Fe3+检测中的应用
Synthesis of rhodamine schiff base fluorescent probe and application thereof in detection of Cu2+ and Fe3+
摘要
Abstract
A rhodamine schiff base fluorescent probe(RBr) was prepared by condensing rhodamine hydrazide with p-bromobenzaldehyde. Its structure was characterized by single crystal XRD and NMR spectroscopy. In aqueous acetonitrile solution,RBr exhibited significant absorbance and fluorescence selectivity for Cu2+ and Fe3+,and there was a good linear relationship between the spectral intensity and ion concentration. The Job’s Plot experiment confirmed that the spirolactam structure of RBr was induced to open upon the coordination of Cu2+/Fe3+,and a 1∶1 metal-probe complex was formed. The absorption intensity of RBr-Cu2+ solution was enhanced under the irradiation of ultraviolet light.关键词
