Catalytic ethylene oligomerization proceeds under mild conditions with high activity using porous or non-porous nickel-based coordination polymers/metal-organic frameworks (MOFs) as catalysts. The role of MOFs as catalyst precursors and the crucial impact of metal coordination on the catalyst activity and leaching are elucidated by comparing MOFs constructed from different clusters and linkers. The stronger the coordination bond of organic linkers to the Ni center, the lower the catalytic activity of the MOF, as shown for CPO-27(Ni). The highest activity and stability were obtained with the [Ni3(ndc)3(DMF)2((CH3)2NH)2]n catalyst.
使用多孔或无孔镍基配位聚合物/金属有机骨架（MOFs）作为催化剂，在温和条件下即可实现催化乙烯齐聚，且具有高活性。通过比较由不同簇和连接体构建的 MOFs，阐明了 MOFs 作为催化剂前体的作用以及金属配位对催化剂活性和浸出的关键影响。有机连接体与 Ni 中心的配位键越强，MOF 的催化活性越低，如 CPO-27（Ni）所示。具有[Ni3（ndc）3（DMF）2（（CH3）2NH）2]n 催化剂时，可获得最高的活性和稳定性。
