A permanently porous, three-dimensional metal-organic material formed from zero-valent metal nodes is presented. Combination of ditopic m-terphenyl diisocyanide, [CNAr], and the d Ni(0) precursor Ni(COD), produces a porous metal-organic material featuring tetrahedral [Ni(CNAr)] structural sites. X-ray absorption spectroscopy provides firm evidence for the presence of Ni(0) centers, whereas gas-sorption and thermogravimetric analysis reveal the characteristics of a robust network with a microdomain N-adsorption profile.
本文报道了一种由零价金属节点形成的具有永久多孔性的三维金属有机材料。通过联苯二异氰酸酯，[CNAr]和 Ni(0)前体 Ni(COD)的组合，生成了一种具有四面体型[Ni(CNAr)]结构位的多孔金属有机材料。X 射线吸收光谱为 Ni(0)中心的存在提供了确凿的证据，而气体吸附和热重分析则揭示了具有微域 N 吸附特性的坚固网络的特征。
