o ‐Carborane, a cluster compound containing boron and adjacent carbon atoms, displays intriguing luminescent properties. Recently, compounds containing o ‐carborane units were found to show suppressed aggregation‐induced quenching and intense solid‐state emission; they also show potential for the development of stimuli‐responsive luminochromic materials. In this Minireview, we introduce three kinds of fundamental photochemical properties: aggregation‐induced emission, twisted intramolecular charge transfer in crystals, and environment‐sensitive excimer formation in solids. Based on these properties, several types of luminochromism, such as thermos‐, vapo‐, and mechanochromism, have been discovered. Based mainly on results from recent studies, we illustrate these mechanisms as well as unique luminescent behaviors of o ‐carborane derivatives.

具有刺激响应性的固态发光邻甲硼烷的最新进展。

o-碳硼烷是一种包含硼和相邻碳原子的簇状化合物，具有令人着迷的发光特性。最近，含有邻发现碳烷单元显示出抑制的聚集诱导的猝灭和强烈的固态发射。它们还显示出刺激响应性光致变色材料的发展潜力。在此Minireview中，我们介绍了三种基本的光化学特性：聚集诱导的发射，晶体中扭曲的分子内电荷转移以及固体中对环境敏感的准分子形成。基于这些特性，已经发现了几种类型的发光变色，例如热水瓶，汽化和机械变色。主要基于最近的研究结果，我们说明了这些机制以及邻碳硼烷衍生物的独特发光行为。
