Water and moisture stability have been recognized as one of the most important characteristics of metal–organic frameworks (MOFs) in regards to their future applications. Nonetheless, most MOFs are water-labile to some degree. One promising solution for the collapse of MOFs toward water is surface hydrophobic modification. Herein, a facile, mild, and general one-step surface polymerization approach has been developed to coat the exterior surface of MOF particles with a thin polymer layer. Remarkably, the hydrophobic layer not only endows water stability of MOFs without significantly disturbing their pore features but also enables the resultant MOFs to retain high catalytic performance for diverse reactions in water.

在有机金属框架（MOF）的未来应用方面，水和水分的稳定性已被视为最重要的特征之一。尽管如此，大多数MOF在一定程度上对水都是不稳定的。MOF向水崩溃的一种有前途的解决方案是表面疏水改性。本文中，已经开发了一种简便，温和且通用的一步式表面聚合方法，以在MOF颗粒的外表面覆盖一层薄的聚合物层。值得注意的是，疏水层不仅赋予了MOFs水稳定性，而没有显着干扰其孔隙特征，而且使所得的MOFs能够为水中的各种反应保留高催化性能。
