The chiral microenvironment around catalytically active metal clusters in a MOF, PCN-222(Cu), is created by simply grafting chiral molecules (R)−C_n−COOH (n=1, 2, 3). Owing to multi-level modulation such as hydrogen interaction, steric hindrance, and confinement effect caused by the microenvironment, the resulting (R)−C_n@PCN-222(Cu) exhibits high activity and enantioselectivity in the asymmetric ring-opening of cyclohexene oxide with aniline.

通过赋予手性微环境开启非手性金属有机框架的不对称催化

MOF PCN-222(Cu) 中催化活性金属簇周围的手性微环境是通过简单地接枝手性分子 ( R )−C _n −COOH ( n =1, 2, 3) 来创建的。由于微环境引起的氢相互作用、空间位阻和限域效应等多级调节，所得的( R )−C _n @PCN-222(Cu)在环己烯的不对称开环中表现出高活性和对映选择性与苯胺氧化。
