We have successfully synthesized rhodium-containing MOFs with 1:1 abundance ratios of paddle-wheel units of Rh2 and Cu2/Zn2, i.e., [Rh2M2(1,4-bdc)4]·nSolvent (M = Cu: RhCu-DMF, RhCu-EtOH; M = Zn: RhZn-DMF; 1,4-bdc: 1,4-benzenedicarboxylate) by a novel synthetic method involving assembly of discrete paddle-wheel dirhodium(II) tetra(1,4-benzenedicarboxylate) with Cu2+ or Zn2+ ions. The diffraction patterns of these complexes were very similar to the predicted and experimental XRPD patterns reported for [Cu2(1,4-bdc)2]. This result indicates that this method enables the incorporation of coordinatively unsaturated noble-metal sites for the many reported MOFs with multi-carboxy ligands and paddle-wheel nodes.
我们成功合成了Rh2和Cu2/Zn2的叶轮单元丰度比为1:1的含铑MOF,即[Rh2M2(1,4-bdc)4]·nSolvent (M = Cu: RhCu-DMF, RhCu-EtOH;M = Zn:RhZn-DMF;1,4-bdc:1,4-苯二甲酸),采用离散桨轮二铑(II)四(1,4-苯二甲酸)与 Cu2+ 组装的新型合成方法或 Zn2+ 离子。这些配合物的衍射图与 [Cu2(1,4-bdc)2] 报道的预测和实验 XRPD 图非常相似。这一结果表明,该方法能够为许多报道的具有多羧基配体和桨轮节点的 MOF 掺入配位不饱和贵金属位点。
