摘要:

通过罗丹明6G和二亚乙基三胺反应制备了一种罗丹明衍生物(ABDO), 利用荧光光谱法和紫外-可见吸收光谱法研究了稀土金属Er与ABDO构成的ABDO-Er配合物随温度变化的趋势. 系统考察了ABDO-Er配合物在恒温水浴中的稳定时间, 对比分析了ABDO-Er配合物、 ABDO及罗丹明6G的荧光强度随温度变化的趋势. 结果表明, ABDO-Er配合物对温度具有线性响应, 可用于监测环境温度的变化.

Abstract:

A rhodamine derivative(ABDO) based on rhodamine 6G and diethylene triamine was synthesized and used as a fluorescent probe to detect temperature. The fluorescence spectra and ultraviolet-visible absorbant spectra were used to study the variation trend of ABDO-Er complex with the temperature. The stabilization time of ABDO-Er complex in constant temperature bath and fluorescence intensity of ABDO-Er complex, ABDO and rhodamine 6G with different temperature were studied. The results showed that ABDO-Er complex was directly proportional to temperature. Therefore, ABDO-Er complex could be used to monitor the change of environmental temperature.

Key words: Temperature, ABDO-Er complex, Fluorescence probe
