摘要

亚稳态光酸（mPAHs）的独特功能是由多个异构体在一个光反应周期内驱动的。对于以苯并咪唑为基础的mPAH，这些包括所描述的反式，顺式，螺旋异构体，以及其他瞬态物种。识别这些瞬态异构体需要具有高时间和频率分辨能力的光学光谱工具，并结合理论计算来实时跟踪光致结构变化。更多的信息可以在y - z的研究文章中找到。马，V. S. Bryantsev和同事（DOI: 10.1002/cphc.202500184）。

Front Cover: Accessing Transient Isomers in the Photoreaction of Metastable-State Photoacid (ChemPhysChem 13/2025)

The unique functionalities of metastable-state photoacids (mPAHs) are driven by multiple isomers during a single cycle of their photoreactions. For a benzimidazole-based mPAH, these include trans, cis, spiro isomers as depicted, along with other transient species. Identification of these transient isomers necessitates an optical spectroscopic tool with high time- and frequency-resolved capabilities in combination with theoretical calculations to follow the photoinduced structural changes in real time. More information can be found in the Research Article by Y.-Z. Ma, V. S. Bryantsev and co-workers (DOI: 10.1002/cphc.202500184).
