新型罗丹明B席夫碱荧光探针的光谱性质研究

摘要

A derivative with Schiff-base structure was synthesized. Fluorescence and visible absorption spectra show that the presence of Fe3+ induces the formation of a Fe3+ complex, observing significant enhancement of fluorescence and absorption.The results show that the derivative is not only a good fluorescence and colorimetric chemosensor for Fe3+ , but also a metal complex fluorescent probe for BSA.%合成了一种席夫碱结构的罗丹明B衍生物.研究表明,该衍生物能与Fe3+形成稳定配合物,同时伴随显著的荧光增敏和吸收增强.衍生物不仅对Fe3+呈现良好的荧光及比色探针性能,其与金属离子形成的配合物也是一种研究牛血清白蛋白的高灵敏荧光探钊.
