Hofmann型磁双稳态材料的设计合成与性能调控

磁双稳态材料由于其显著的磁行为调控与响应效应在未来的信息存储、传感器、分子开关等领域有着潜在的重要应用价值，如何设计合成出能在接近或高于室温区间工作的磁双稳态材料至关重要，是磁化学与磁物理、材料学科交叉前沿研究的重要挑战之一。本项目以定向设计主客体协同响应的自旋交叉材料为目标导向，在良好的前期基础上，主要构筑Hofmann型自旋转换MOF体系。以现代表征技术，跟踪上述目标物对外界多种刺激诱导（如热/光/压力以及光活性分子变换、主客体作用等）下的响应行为和应答机制，探索协同效应所导致的新奇物理现象和潜在的新用途，探寻具有存储和开关功能的新型多步自旋转换体系。

Magnetic bistable materials have important potential application in the field of future memory and switching functions, which could ultimately be utilized for the elaboration of molecule-based devices. The contemporary exploitation of magnetic bistable materials that work at near or above room temperature is a particularly promising field both at fundamental and applied levels. This project aims at exploration of the rational design of spin-crossover (SCO) materials with host-guest synergistic response. Based on the understanding of the relation between the functionalities and the structural parameters, we will focus on the design and construction of Hofmann-type SCO-active metal-organic framework (MOF) materials, and the exploration of the basic structural requirement for combining the SCO behaviors and the novel physical phenomena as well as potential application. The results will be published in international mainstream scientific journals.
