摘　　要：Color-tunable smart-responsive organic emitters (CSOEs) represent a cutting-edge category of intelligent optoelectronic materialswidely recognized for their remarkable ability to adjust emissioncolors in response to a range of external stimuli, including excitation light, temperature, external force, and specific matter. The versatile nature of CSOEs has recently attracted significant attentionfor their unique properties, including the ability to reversibly tunecolors in response to different stimuli. Their superior responsiveness and dynamic color-changing capabilities extend beyond theperformance of traditional luminescent materials, making themhighly suitable for potential applications in multicolor displays,information encryption, and visual sensing. CSOEs have been successfully developed in various forms, including small molecules,polymers, and host–guest materials. Despite significant progressin this area, there is still a need for a comprehensive understandingof the material design and development pathways for CSOEs. Thisperspective highlights the importance of in-depth analyses ofdesign strategies and fundamental mechanisms (Fig. 1) to offerinsights that can facilitate the creation of CSOEs and effectivelyextend their applications.
