The first examples of monolithic crystalline host-guest hybrid materials are described. The reaction of 1,3,5-benzenetricarboxylic acid (H BTC) and Fe(NO ) ⋅9 H O in the presence of decamethylcucurbit[5]uril ammonium chloride (MC5⋅2 NH Cl⋅4 H O) directly affords MC5@MIL-100(Fe) hybrid monoliths featuring hierarchical micro-, meso- and macropores. Particularly, this "bottle-around-ship" synthesis and one-pot shaping are facilitated by a newly discovered Fe-MC5 flowing gel formed by mechanochemistry. The designed MC5@MIL-100(Fe) hybrid material with MC5 as active domains shows enhanced CH and lead(II) uptake performance, and selective capture of lead(II) cations at low concentrations. This shows that host-guest hybrid materials can exhibit synergic properties that out-perform materials based on individual components.
本文描述了首例整体式晶体主客体杂化材料。在十甲基瓜环[5]脲氯化铵（MC5·2NH4Cl·4H2O）存在下，1,3,5-苯三甲酸（H3BTC）与Fe(NO3)3·9H2O反应直接生成具有分级微孔、介孔和大孔的MC5@MIL-100(Fe)杂化整体材料。特别地，这种“瓶中船”合成法和一锅成型法借助机械化学新发现的Fe-MC5流动凝胶得以实现。以MC5作为活性域设计的MC5@MIL-100(Fe)杂化材料表现出增强的CH4和铅（II）吸附性能，以及在低浓度下对铅（II）阳离子的选择性捕获。这表明主客体杂化材料可展现出优于基于单一成分材料的协同性能。
