Abstract

Phase transfer of metal-organic frameworks is highly desired in many areas, which remains a challenge. Herein, we present for the first time a CO-driven reversible transfer of amine-functionalized ZIF-90 between organics and water. A mechanistic study showed that the switching is ascribed to the reversible generation of hydrophilic ammonium salts from the reaction of CO with the amines on ZIF-90. This unique system has been used for the coupling of -esterification reactions, product separation and component recycling for green sustainable processes. This work opens up a new avenue for performing reactions effectively with an easy separation process.

摘要

金属有机框架的相转移在许多领域都备受期待，但仍然是一个挑战。在此，我们首次展示了一种由CO驱动的胺功能化ZIF-90在有机物和水之间的可逆转移。机理研究表明，这种转变归因于CO与ZIF-90上的胺反应可逆地生成亲水性铵盐。这个独特的体系已被用于酯偶联反应、产物分离以及绿色可持续过程中的组分循环利用。这项工作为通过简便的分离过程有效进行反应开辟了一条新途径。
