含配位空腔的配位笼玻璃体的设计合成与应用

纳米尺度的配位空腔在催化、分离、吸附等领域都有很好的应用价值。除了微观的分子结构，材料的宏观结构对于材料的应用也至关重要，因此，材料的可塑性引起人们的重视。本项目中，申请人提出结合配位笼的功能配位空腔与玻璃体材料的可塑性，构筑含配位空腔的配位笼玻璃体。项目将设计合成主体结构相同而外围小分子取代基种类和数量不同的系列配位笼，通过外围基团的调控调节配位笼固体的结构，并以“熔融-冷却”和机械研磨等方法实现固体的玻璃化，获得配位笼玻璃体。在此基础上，系统研究配位笼分子结构及相互作用等与材料玻璃化能力之间的关系，提出配位笼玻璃体的构筑策略。对配位笼玻璃体进行结构、基本物化性能以及在色谱分离和水中污染物吸附方面的应用研究并分析构效关系。项目完成后，将发展一类新型的玻璃体材料，架构配位笼分子与材料之间的新桥梁，为配位笼材料的应用提供新的可能。

Nanoscale coordination cavity has potential applications for catalysis, recognition, separation, adsorption and so on. In addition to the molecular structures, the macro structures of materials are also very important to their real applications. Therefore, the processability of materials has attracted much attention. In this project, we propose to construct coordination cage-based glass by combining the function of coordination cavities in coordination cages and the excellent processability of glass materials. First, a series of coordination cages with the same parent structure and different peripheral substituents will be designed and synthesized, and the structure of the resulted coordination cage-based solid will be regulated through the regulation of peripheral groups. Then, the synthesis of coordination cage-based glass will be realized by means of "melting-quenching", mechanical milling, and so on. Second, the relationship between the structures and interactions of coordination cages and the glass ability of the materials will be studied and the construction strategy of coordination cage-based glass will be proposed. The structures, properties and applications on chromatographic separation and pollutant adsorption in water of the selected coordination cage-based glasses will be studied. After the completion of the project, a new type of glass will be developed to build a new bridge between coordination cage molecules and materials, providing new possibilities for the application of coordination cage-based materials.
