通过选择不同的溶剂/模板剂，制备出具有sql、SOD、RHO等三种不同拓扑网络结构的苯并咪唑锌框架，并探究荧光分子苝在这三种金属多氮唑框架材料中的封装情况，以实现对挥发性有机化合物的荧光传感。该实验利用X射线粉末衍射法鉴定产物的结构和纯度，通过荧光光谱法对反应产物发光性能进行分析，利用紫外-可见光谱法测定苝的封装量。该实验的操作简单，重现性好，反应快速，条件温和、绿色，几乎不产生会造成环境污染的副产物。因此，该实验作为本科教学实验可实施性强。在三种金属多氮唑框架材料的合成、表征、性能探究的实验流程中，加入平行对比实验，能加深学生对配位化学合成理论与多孔材料性能的理解，也能培养学生对实验数据的分析能力。此外，将多孔框架材料的合成与荧光分子的封装相结合实现荧光传感效果，能提升实验的趣味性，有利于激发学生对材料性能与应用的探索精神。
