Two isostructural lanthanide metal–organic frameworks (Ln-MOF-589, Ln = La3+, Ce3+), constructed from a tetratopic linker, benzoimidephenanthroline tetracarboxylic acid (H4BIPA-TC), have been solvothermally synthesized and characterized. These Ln-MOF-589 materials consist of Lewis acid [Ln2(-COO)6(-COOH)2(H2O)6] units and a naphthalene diimide core, which exhibited promising catalytic activity for the oxidation of olefins. Among them, Ce-MOF-589 exhibited outstanding performance with high conversions of styrene and cyclohexene (94 and 90%, respectively), and good selectivities towards styrene oxide and 2-cyclohexen-1-one (85, and 95%, respectively). Notably, the catalytic activity of Ce-MOF-589 outperformed that of homogeneous and heterogeneous catalysts, and representative MOFs. Also, Ce-MOF-589 can be recycled for at least up to six cycles with no significant loss of catalytic performance.

镧系金属-有机化合物催化烯烃的氧化

溶剂热合成和表征了由四位接头苯并酰亚胺亚菲咯啉四羧酸(H 4 BIPA-TC)构成的两个同构镧系金属有机骨架(Ln-MOF-589,Ln = La 3+,Ce 3+)。这些Ln-MOF-589材料由路易斯酸[Ln 2(-COO)6(-COOH)2(H 2 O)6组成单元和萘二酰亚胺核,它们对烯烃的氧化显示出有希望的催化活性。其中,Ce-MOF-589具有出色的性能,其中苯乙烯和环己烯的转化率很高(分别为94%和90%),并且对氧化苯乙烯和2-环己烯-1-酮的选择性很好(分别为85%和95%) 。值得注意的是,Ce-MOF-589的催化活性优于均相和非均相催化剂以及代表性的MOF。另外,Ce-MOF-589至少可以循环使用六个周期,而催化性能不会显着降低。
