o-Carborane is an icosahedral cluster containing boron and has been paid attention as a versatile platform for constructing stimuli-responsive materials with solid-state luminescence properties by suppressing aggregation-caused quenching (ACQ), which is the emission annihilation process observed in condensed states, such as concentrated solutions, solids and films. Non-specific intermolecular interactions in the condensed states resulting in ACQ are disturbed by the spherical boron cluster. More recently, it has been demonstrated from several reports that o-carborane is capable of assisting solid-state excimer emission in aryl-modified o-carboranes. Moreover, some of these materials provide unique stimuli-responsiveness. In the commodity design for solid-state luminescent materials, o-carboranes are responsible for disturbing intermolecular interactions and subsequently presenting solid-state luminescence. On the other hand, excimer emission, which is inducible from the intermolecular photophysical process, has been discovered in the solid state based on o-carborane materials. In this manuscript, recent progress in stimuli-responsive luminescent materials via excimer formation will be described. Moreover, as the further potential of o-carborane materials, recent findings on the photo-salient effect which can be induced through excimer formation followed by photoreaction will also be explained.

邻碳硼烷衍生物的固态准分子发射及其在刺激响应发光材料中的应用

o-碳硼烷是一种含有硼的二十面体簇，通过抑制聚集引起的猝灭（ACQ）（在凝聚态中观察到的发射湮没过程），作为构建具有固态发光特性的刺激响应材料的通用平台而受到关注。 ，例如浓缩溶液、固体和薄膜。导致 ACQ 的凝聚态非特异性分子间相互作用受到球形硼簇的干扰。最近，一些报道已经证明邻碳硼烷能够辅助芳基改性的邻碳硼烷中的固态准分子发射。此外，其中一些材料提供独特的刺激响应性。在固态发光材料的商品设计中，邻碳硼烷负责干扰分子间相互作用并随后呈现固态发光。另一方面，在基于邻碳硼烷材料的固态中，已经发现了由分子间光物理过程诱导的准分子发射。在这份手稿中，将描述通过准分子形成刺激响应发光材料的最新进展。此外，作为邻碳硼烷材料的进一步潜力，还将解释通过准分子形成随后进行光反应而诱发的光显着效应的最新发现。
