A glycoluril-derived molecular-clip-based supramolecular organic framework (clip-SOF) with intrinsic porosity was prepared. The clip-SOF was used for the adsorption and removal of 2,4,6-trinitrotoluene (TNT) driven by noncovalent interactions. The efficiency of TNT removal by clip-SOFs is up to 88.5% in adsorption equilibrium, and the TNT adsorption capacity of clip-SOFs is about 40.2 mg/g at 25.0 °C. Clip-SOFs have good reusability, exhibiting almost no loss in performance in ten consecutive recycling tests. This work not only provides a new method for adsorbing energetic materials, but also promotes the application of supramolecular hosts in crystal engineering.
制备了一种具有固有孔隙率的基于甘脲衍生分子夹的超分子有机框架（分子夹-SOF）。该分子夹-SOF用于通过非共价相互作用吸附和去除2,4,6-三硝基甲苯（TNT）。在吸附平衡时，分子夹-SOF去除TNT的效率高达88.5%，在25.0℃时分子夹-SOF对TNT的吸附容量约为40.2 mg/g。分子夹-SOF具有良好的可重复使用性，在连续十次循环测试中性能几乎没有损失。这项工作不仅为吸附含能材料提供了一种新方法，还推动了超分子主体在晶体工程中的应用。
