我们报告了一种通过 MOF 在纳米颗粒上自组装来合成无机纳米颗粒/金属有机框架 (MOF) 异质结构纳米复合材料的新方法。该方法涉及Au纳米颗粒的合成以及由Cu(2+)离子和1,3,5-三羧酸苯(btc)组成的[Cu(3)(btc)(2)](n)框架在纳米颗粒上的优先生长。由Cu(2+)离子连接的11-巯基十一烷酸(MUA)稳定的Au纳米颗粒组成的聚集体对于聚集体上[Cu(3)(btc)(2)](n)框架的优先自组装是必要的，从而形成Au纳米颗粒/[Cu(3)(btc)(2)](n)纳米复合材料。本方法被证实适用于由金纳米粒子和四方[Cu(2)(ndc)(2)(dabco)](n)框架组成的其他杂化物。
We report a novel approach for synthesizing inorganic nanoparticle/metal-organic frameworks (MOFs) heterostructured nanocomposites by self-assembly of MOFs on nanoparticles. This approach involves the synthesis of Au nanoparticles and preferential growth of [Cu(3)(btc)(2)](n) frameworks consisting of Cu(2+) ions and benzene-1,3,5-tricarboxylate (btc) on nanoparticles. Aggregates consisting of 11-mercaptoundecanoic acid (MUA)-stabilized Au nanoparticles linked by Cu(2+) ions were necessary for preferential self-assembly of [Cu(3)(btc)(2)](n) frameworks on the aggregates, resulting in the formation of Au nanoparticles/[Cu(3)(btc)(2)](n) nanocomposites. The present approach was confirmed to be applicable for other hybrids consisting of Au nanoparticles and tetragonal [Cu(2)(ndc)(2)(dabco)](n) frameworks.
