This Minireview summarizes the recent progress of stimuli-responsive purely organic phosphorescence materials. Organic phosphorescence is closely related to the intermolecular interactions, because such interactions are beneficial to promote spin orbital coupling (SOC) and boost intersystem cross (ISC) efficiency and finally are conducive to satisfactory phosphorescence. It is found that the intermolecular interactions, which are essential for organic phosphorescence, are easily disturbed by external stimuli such as mechanical force, photon, acid, chemical vapor, leading to the luminescence change. According to this principle, various purely organic phosphorescence materials sensitive to external stimuli have been developed. This Minireview categorizes reported stimuli-responsive purely organic phosphorescence materials on the basis of different stimuli, including mechanochromism, mechanoluminescence, photoactivity, acid-responsiveness and other stimuli. Some prospective strategies for constructing stimuli-responsive purely organic phosphorescence molecules are provided.
本综述总结了刺激响应型纯有机磷光材料的最新进展。有机磷光与分子间相互作用密切相关，因为这种相互作用有利于促进自旋轨道耦合（SOC）并提高系间窜越（ISC）效率，最终有利于产生令人满意的磷光。研究发现，对于有机磷光至关重要的分子间相互作用很容易受到外力、光子、酸、化学蒸汽等外部刺激的干扰，从而导致发光变化。根据这一原理，已经开发出了各种对外部刺激敏感的纯有机磷光材料。本综述根据不同的刺激，包括机械变色、机械发光、光活性、酸响应性和其他刺激，对已报道的刺激响应型纯有机磷光材料进行了分类。还提供了一些构建刺激响应型纯有机磷光分子的前瞻性策略。
