Reported here are the bottom-up synthesis and structural analysis as well as the adsorption property investigation of a series of isostructural metal-organic frameworks based on carborane backbones and Cu(2)(CO(2))(4) units. All these compounds are 2D grid structures composed of four component rings. Using linear p-CDC (p-CDCH(2) = 1,12-dihydroxycarbonyl-1,12-dicarba-closo-dodecaborane) as a backbone, only one type of ring formed. However, five types of rings may exist when m-CDCH(2) (m-CDCH(2) = 1,7-dihydroxycarbonyl-1,7-dicarba-closo-dodecaborane) was used due to its varied orientation. Here, the solvent molecules play a key role in the formation of these compounds and the expected five types of rings were obtained. The gas sorption properties of compounds 5' and 8' were studied. These frameworks preferentially adsorb CO(2) over both CH(4) and N(2) due to the coordinatively unsaturated copper ions.
本文报道了一系列基于碳硼烷骨架和 Cu(2)(CO(2))(4)单元的同构金属有机骨架的自下而上合成、结构分析以及吸附性能研究。这些化合物均为二维网格结构，由四个组成环组成。使用线性 p-CDC（p-CDCH(2)=1,12-二羟基羰基-1,12-二碳杂-closo-十二硼烷）作为骨架，仅形成一种类型的环。然而，当使用 m-CDCH(2)（m-CDCH(2)=1,7-二羟基羰基-1,7-二碳杂-closo-十二硼烷）时，由于其不同的取向，可能存在五种类型的环。在这里，溶剂分子在这些化合物的形成中起着关键作用，并且得到了预期的五种类型的环。对化合物 5'和 8'的气体吸附性能进行了研究。由于配位不饱和的铜离子，这些骨架优先吸附 CO(2)而不是 CH(4)和 N(2)。
