One of the dominant types of interactions between host and guest molecules is hydrogen-bonding, and these interactions can work selectively for a guest molecule. Here, we demonstrate a metal-organic framework (MOF) having both hydrogen-bonding donor and acceptor sites that are quite effective for selective sorption. The MOF selectively interacts with hydroxylic guests in contrast to aprotic hydrogen-bonding guests and shows a sorption selectivity for protic H(2)O, MeOH, and EtOH guests. Notably, this is the first compound that shows complete selectivity in adsorption not for MeCN and MeCHO but for EtOH, which has similar fundamental properties except for its proticity.

嵌入层状金属-有机框架中的氢键供体和受体位点对羟基的识别

主体和客体分子之间的主要相互作用类型之一是氢键，这些相互作用可以选择性地作用于客体分子。在这里，我们展示了一种具有氢键供体和受体位点的金属有机骨架 (MOF)，它们对选择性吸附非常有效。与非质子氢键客体相比，MOF 选择性地与羟基客体相互作用，并显示出对质子 H(2)O、MeOH 和 EtOH 客体的吸附选择性。值得注意的是，这是第一个在吸附中表现出完全选择性的化合物，不是对 MeCN 和 MeCHO，而是对 EtOH，除了其质子性外，它具有相似的基本特性。
