Stimuli-responsive luminescent materials are an important class of smart materials whose luminescent properties are intelligently changed in response to external stimuli. They have a wide variety of applications in anti-counterfeit, sensing systems and information storage, and so on. The research project is planned to systemically and thoroughly study on the external stimuli-responsive properties of the new kinds of luminescent materials, elucidate their stimuli-responsive mechanisms, get the internal relationship and rules, and explore their applications. The research plan identifies three priority research areas, including: 1) design and synthesis of new kinds of luminescent materials based on dual emission (fluorescence-phosphorescence, fluorescence-thermally activated delayed fluorescence, and fluorescence-long afterglow), systematic investigation on the relationships between molecular structures and properties, and the exploration of their emissive mechanisms; 2) systematic investigation of their stimuli-responsive mechanisms; 3) on the basis of a complete analysis and explanation of the relationship of molecular structure, aggregation structure and stimuli-responsive luminescent properties, we will further carry out the applied research of the smart materials in the fields of anti-counterfeit, sensing systems, information storage, and so on. Through this research project, we will lay a solid practical and theoretical basis for development of the new smart materials with multi-stimuli-responsive and wide variation of wavelength natures in the future. Through this study, we hope to provide theoretical bases and new strategies for new kinds of stimuli-responsive luminescent smart materials, and lay a solid foundation for their practical applications through significant breakthrough in application study.
