本文首先介绍了激发态分子内质子转移（ESIPT）发色团的基本光物理性质，然后综述了ESIPT发色团的最新研究进展及其在化学传感器、生物成像和白光发射材料中的应用。ESIPT发色团的大多数应用都是基于光物理性质，例如通过干扰ESIPT过程与分析物相互作用来设计荧光化学传感器，通过探测水合作用的变化将其用作生物荧光标签来研究dna -蛋白质相互作用，或者利用ESIPT发色团的大Stokes位移（抑制Föster组件的能量转移）来设计白光发射材料。讨论了这些应用的光物理机理。在此基础上，提出了一个关于ESIPT发色团的新研究课题，即利用ESIPT发色团开发有机三重态敏化剂。
In this perspective we introduce the basic photophysics of the excited-state intramolecular proton transfer (ESIPT) chromophores, then the state-of-the-art development of the ESIPT chromophores and their applications in chemosensors, biological imaging and white-light emitting materials are summarized. Most of the applications of the ESIPT chromophores are based on the photophysics properties, such as design of fluorescent chemosensors by perturbation of the ESIPT process upon interaction with the analytes, their use as biological fluorescent tags to study DNA-protein interaction by probing the variation of the hydration, or design of white-light emitting materials by employing the large Stokes shift of the ESIPT chromophores (to inhibit the Föster energy transfer of the components). The photophysical mechanism of these applications is discussed. Furthermore, a new research topic concerning the ESIPT chromophores is proposed based on our group's results, that is, to develop organic triplet sensitizers with ESIPT chromophores.
