Organic room temperature 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. The 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. For more information, see the Minireview by Z. Ma et al. on page 11914 ff.
