Abstract

Ultralong organic room temperature phosphorescence (RTP) materials are highly promising for various applications. Particularly, dynamic stimulus-responsive RTP materials are suitable for diverse cutting-edge technologies and meet practical needs, owing to the good reversibility, fast response and tunable luminescence ability. Host-guest doping systems provide a more competitive and promising strategy for the construction of stimulus-responsive RTP materials, because the characteristics of the host or guest and the intermolecular interactions between host and guest gives them dynamic reversible and stimulus-responsive property. In this review, we not only summarize recent progress of stimulus-responsive RTP materials based on host-guest doping systems, but also highlight the changes in intermolecular interaction, conformation, chemical structure and oxygen concentration playing the important role in corresponding stimulus-responsive RTP properties. Finally, the prospects and scientific challenges in this emergent field are discussed to provide helpful guidance for further development of advanced stimulus-responsive RTP materials based on host-guest systems.

基于主客体掺杂系统的刺激响应型室温有机磷光材料

超长有机室温磷光（RTP）材料具有广泛的应用前景。特别是动态刺激响应RTP材料，其可逆性好、响应速度快、发光能力可调，适用于多种前沿技术，满足实际需要。主客体掺杂体系为构建刺激响应RTP材料提供了一种更具竞争力和前景的策略，因为宿主或客体的特性以及宿主和客体之间的分子间相互作用赋予了它们动态可逆和刺激响应的特性。本文综述了近年来基于主客体掺杂体系的刺激响应型RTP材料的研究进展，重点介绍了分子间相互作用、构象、化学结构和氧浓度的变化对刺激响应型RTP材料性能的影响。最后，讨论了这一新兴领域的前景和科学挑战，为进一步开发基于主客体系统的先进刺激响应RTP材料提供有益的指导。

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
