激发态分子内质子转移型离子探针的研究进展

摘要

Excited state intramolecular proton transfer (ESIPT),is a special excited state photophysical processes.An important fea-ture of the process occurs usually tautomerism in the detur proton groups ,such as enol transfer to keto tautomerization in the excited state,leading to great stokes shift.So compounds with ESIPT properties are used as good fluorescent probes and photochromic mate -rials.Combined with the latest domestic and international research work ,the development of fluorescent probes of anions and cations based on ESIPT were summarized.And the structure,woking mechanism,existing issues and prospects were discussed in the field.%激发态分子内的质子转移（ESIPT），是特殊的激发态光物理过程，此过程中的一个重要特征就是给质子基团通常会发生互变异构现象，如烯醇在激发态时发生烯醇式向酮式的转变，导致这类化合物具有很大的斯托克斯位移（Stokes shift），是良好的荧光探针或光致变色材料。本文结合国内外最新研究工作，综述了基于ESIPT机理在阴、阳离子荧光探针的研究进展；并对ESIPT分子结构的特点、工作原理、存在的问题及其应用前景作了评述。
