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.
在这篇观点文章中，我们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，然后总结了 ESIPT 发色团的最新发展及其在化学传感器、生物成像和白光发光材料中的应用。ESIPT 发色团的大多数应用都是基于光物理性质的，例如通过与分析物相互作用干扰 ESIPT 过程来设计荧光化学传感器，将其用作生物荧光标记物通过探测水合作用的变化来研究 DNA-蛋白质相互作用，或者通过利用 ESIPT 发色团的大斯托克斯位移来设计白光发光材料（以抑制组分的福斯特能量转移）。我们讨论了这些应用的光物理机制。此外，根据我们小组的结果，提出了一个与 ESIPT 发色团有关的新研究课题，即开发具有 ESIPT 发色团的有机三重态敏化剂。
