在这项工作中，我们报道了一种由对称的四甲基葫芦[6]脲(TMeQ[6])在盐酸水溶液中构建的多孔超分子骨架(A)，驱动力是葫芦[n]脲的外表面相互作用，以及TMeQ[6]的网状水分子与门式羰基氧原子之间的氢键。吸附实验结果表明，多孔超分子骨架可以通过荧光增强或变色吸附某些荧光团客体(FGs)形成发光组件(FG@As)，其中一些可以对某些挥发性有机化合物产生响应。因此，基于TMeQ[6]的超分子骨架可以用作某些气体或挥发性化合物的传感器。
In this work, we reported a porous supramolecular framework (A) constructed of a symmetric tetramethylcucurbit[6]uril (TMeQ[6]) in aqueous HCl solutions; the driving force was the outer surface interaction of cucurbit[n]urils, as well as hydrogen bonding between latticed water molecules and portal carbonyl oxygens of TMeQ[6]. Adsorption experimental results revealed that the porous supramolecular framework can absorb certain fluorophore guests (FGs) to form luminescent assemblies (FG@As) by fluorescence enhancement or colour change, and some of them can respond to certain volatile organic compounds. Thus, the TMeQ[6]‐based supramolecular framework could be used as a sensor for certain gas or volatile compounds.
