references, multifunctional MOFs with high catalytic performance could be constructed from the combination of metal cations and polycarboxyl-pyridine ligands, which could efficiently endow crystallized porous frameworks with the coexisting Lewis acid-base properties. Thus, by employing a ligand-directed synthetic strategy, the exquisite combination of wave-like inorganic chains of [Tm(CO2)3(OH2)]n and
根据文献记载,可以通过金属阳离子和聚羧基吡啶配体的组合来构建具有高催化性能的多功能MOF,它们可以有效赋予结晶的多孔骨架以同时存在的路易斯酸碱性质。因此,通过使用配体定向合成策略,精致组合波浪状的无机链〔TM(CO 2)3(OH 2)] Ñ和〔TM(CO单核单元2)4(OH 2)2借助特别设计的2,6-双(2,4-二羧基苯基)-4-(4-羧基苯基)吡啶(H 5BDCP)产生了一种高度坚固的(Me 2 NH 2)[Tm 3(BDCP)2)(H 2 O)3 ]·4DMF·H 2 O} n(简化为NUC-25)n的微孔构架,其中包含-矩形纳米通道和大量溶剂残留空隙。此外,由于路易斯酸碱位点(包括6位配位的Tm 3+离子,未配位的羧基氧原子和N吡啶)共存,因此NUC-25的活化状态以及相关水分子的去除是很少报道的双功能多相催化剂。原子。正如预期的那样,NUC-25在无溶剂的条件下,对环氧化物与CO
