Herein, a new preparation strategy of chiral metal–organic frameworks (CMOFs) has been demonstrated. By adsorption and then post-synthetically modified (PSM) procedures, chiral salen(Co(III)) could be imprisoned within the cages of an MOF and remained in its free form. This is the first report on the successful application of CMOFs in heterogeneous asymmetric catalysis for coupling CO₂ with epoxides to obtain optically active cyclic carbonates at room temperature.

Salen（Co（III））通过合成后修饰及其在室温下固定CO _2的不对称催化作用而被囚禁在金属有机骨架的孔中

在这里，已经证明了一种新的手性金属-有机骨架（CMOFs）的制备策略。通过吸附然后进行合成后修饰（PSM），手性Salen（Co（III））可以被囚禁在MOF的笼子中，并保持其自由状态。这是关于CMOF在非均相不对称催化中成功应用的报道，该催化用于在室温下将CO ₂与环氧化物偶联以获得光学活性的环状碳酸酯。
