Smart Responsive Organic Emitters: Intrinsic Mechanisms and Versatile Applications

Abstract Smart responsive organic emitters, which exhibit tunable emission properties in response to external stimuli, can serve as a new generation of intelligent optoelectronic materials because of their versatile applications, such as multicolor displays, information encryption, visual sensing, and matter detection. In recent years, significant advancements have been made in the development of smart responsive organic emitters. However, there is still a lack of a systematic review that provides a comprehensive insight into smart responsive organic emitters from the perspectives of intrinsic mechanisms and versatile applications. Hence, this review concentrates on analyzing the intrinsic mechanisms, which can clarify the relationships between material systems and tunable emission behaviors. This process can provide helpful design principles for smart responsive organic emitters. Furthermore, versatile smart applications have been highlighted to deepen the understanding of the practical values of such smart responsive emitters. This work summarizes the state‐of‐the‐art progress of smart responsive emitters and highlights the existing challenges and future development directions. It aims to provide inspiration and guidelines for the construction of novel smart responsive organic emitters, thereby broadening and stimulating their prominent applications in various fields such as electronic information and flexible electronics.
