Stimuli‐Responsive Dual‐Emission Property of Single‐Luminophore‐Based Materials

Abstract Single luminophore enabling stimuli‐responsive dual‐emission characteristic has received considerable interest in recent years due to its special advantages in advanced optical events. A large number of reports around the globe have involved the dynamic or adjustable dual‐emission phenomenon (e.g., the dual emission intensity or ratio) in single‐emitter based systems. However, a systematic overview summarizing the underlying mechanisms, stimuli‐responsive behaviors, and applications of this topic is, so far, missing. To further promote the development and extend the important role of such a kind of materials in diverse communities, in this review, the latest advancements in the field of single‐luminophore based materials that exhibit stimuli‐responsive dual‐emission characteristics are summarized. The discussion is centered on the underlying the photophysical mechanisms, the innovative design approaches, strategies for modulating the dual emission properties, and the advanced applications of these single‐luminophore based systems. This review is anticipated to provide new insights into the distinctive field of the organic luminescence community from a materials perspective.
