A mixed-ligand metal-organic framework (MOF) material composed of both amine- and hydroxyl-bearing linkers, KSU-1, was reacted with a variety of isocyanates. The hydroxyl groups reacted to a greater extent than the amines, in conflict with the previously observed relative nucleophilicities of these functionalities in the same MOF. When immobilized individually in monofunctional MOFs, the amine-functionalized linker was more reactive than the hydroxyl linker, indicating that the reactivity reversal observed in KSU-1 is due to the groups' mutual confinement within the MOF.
一种由含胺和含羟基的连接体组成的混合配体金属有机框架（MOF）材料KSU - 1，与多种异氰酸酯发生了反应。羟基的反应程度比胺更大，这与之前在同一MOF中观察到的这些官能团的相对亲核性相矛盾。当单独固定在单官能团MOF中时，胺官能化连接体比羟基连接体更具反应性，这表明在KSU - 1中观察到的反应性反转是由于这些基团在MOF内的相互限制。
