We herein reported a design strategy for the construction of resorcin[4]arene-based metal–organic complexes through adjusting auxiliary linkers. By precisely tuning 1,4-benzenedicarboxylic acid analogs, a series of isostructural resorcin[4]arene-based metal–organic dimers, namely, [Zn4(TIC4R)2·(L)2·(OH)2]·2HCOO·solvent (1–9) (L = 1,4-benzenedicarboxylic acid analogs and TIC4R = tetra(imidazole)resorcin[4]arene), were rationally prepared under solvothermal conditions. Considering the amino groups on the backbone of dimer 2, Pd nanoparticles were prepared to uniformly disperse on the substrate of 2 to give Pd@2. Most importantly, the Pd@2 catalyst was applied for nitroarene hydrogenation with efficient catalytic performance and high selectivity under mild conditions. This work afforded a possible method for precisely controlling the target complex assemblies and their further application.

锚定在间苯二酚[4]芳烃基含氨基金属有机二聚体上的高度分散的钯纳米颗粒催化硝基芳香族化合物的氢化



我们在此报告了一种通过调整辅助连接体构建间苯二酚[4]芳烃基金属有机配合物的设计策略。通过精确调控1,4-苯二甲酸类似物,得到一系列同构间苯二酚[4]芳烃基金属有机二聚体,即[Zn 4 (TIC4R) 2 ·( L) 2 ·(OH) 2 ]·2HCOO·溶剂 (1–9) (L = 1,4-苯二甲酸类似物,TIC4R = 四(咪唑)间苯二酚[4 ]芳烃),在溶剂热条件下合理制备。考虑到二聚体2主链上的氨基,制备Pd纳米粒子均匀分散在2的基底上,得到Pd@2。最重要的是,Pd@2催化剂应用于硝基芳烃加氢,在温和条件下具有高效的催化性能和高选择性。这项工作为精确控制目标复杂组件及其进一步应用提供了一种可能的方法。
