Abstract Metal-organic frameworks are booming development as porous crystalline materials and immensely attract lots of interest all around the world. A novel 3D Co-based MOF was successfully prepared by assembling Co(II) and H5tbdpb under solvothermal method. The as-made sample was investigated and characterized by many testing methods. Notably, uncoordinated carboxylic acids were reserved in the porous skeleton. By virtue of porous structure, CO2 adsorption capacity, and two catalytic centers of –COOH as Bronsted acid and Co(II) as Lewis acid, this MOF is able to high-efficiently fix CO2 and various epoxides to cyclic carbonates with preferable recyclability.

构建 3D 多孔 Co(II)-有机骨架：环氧化物和 CO2 的合成、表征和化学转化为环状碳酸酯

摘要 金属有机骨架作为多孔结晶材料得到了蓬勃发展，引起了全世界的广泛关注。通过在溶剂热法下组装 Co(II) 和 H5tbdpb，成功制备了一种新型的 3D Co 基 MOF。通过许多测试方法对制成的样品进行了研究和表征。值得注意的是，未配位的羧酸被保留在多孔骨架中。凭借多孔结构、CO2 吸附能力以及作为布朗斯台德酸的 –COOH 和作为路易斯酸的 Co(II) 的两个催化中心，该 MOF 能够高效地将 CO2 和各种环氧化物固定为环状碳酸酯，并且具有较好的可回收性。
