Abstract The development of stimulus‐responsive phosphorescent materials has attracted increasing attention owing to their advantages in practical applications. However, those responses toxic and hazardous chemicals remain rare the lack suitable design strategies. Herein, a new approach regulate room‐temperature phosphorescence (RTP) effect doping systems is developed, which two polar phenothiazine derivatives functionalized with trifluoroacetyl groups act as guests polymer matrices different polarities function hosts. Regulated by host, transition from aggregation dispersion can be realized for guest molecules, resulting enhanced RTP. Unlike traditional materials, doped system undergo dynamic state upon exposure hydrazine hydrate vapor, thereby activating phosphorescence. Building on these findings, an effective model established investigate effects transitions between aggregated dispersed states. A novel sensor developed detect hydrates.
