The catalytic performance of metal–organic frameworks (MOFs) for the synthesis of cyclic carbonate from carbon dioxide and epoxides has been explored under solvent and solvent‐free conditions, respectively. It was found that MOF catalysts have significantly improved catalytic activities in solvent‐free CO₂ cycloaddition reactions than those in solvent. The mechanism was discussed with regard to the competition of solvent with substrate to adhere MOF catalysts during the reaction process.

溶剂阻碍金属有机框架上的CO2环加成反应

分别在无溶剂和无溶剂条件下研究了金属有机骨架（MOF）从二氧化碳和环氧化物合成环状碳酸酯的催化性能。结果发现，MOF催化剂在无溶剂的CO ₂环加成反应中比在溶剂中的催化活性大大提高。讨论了在反应过程中溶剂与底物竞争粘附MOF催化剂的机理。
