The two-dimensionally connected metal-organic frameworks (MOFs) Ni(HIB) and Cu(HIB) (HIB = hexaiminobenzene) are bulk electrical conductors and exhibit ultraviolet-photoelectron spectroscopy (UPS) signatures expected of metallic solids. Electronic band structure calculations confirm that in both materials the Fermi energy lies in a partially filled delocalized band. Together with additional structural characterization and microscopy data, these results represent the first report of metallic behavior and permanent porosity coexisting within a metal-organic framework.
二维连接的金属-有机骨架（MOFs）Ni（HIB）和 Cu（HIB）（HIB = 六亚甲基苯）是体电导导体，并表现出金属固体的紫外光电子能谱（UPS）特征。电子能带结构计算证实，在这两种材料中，费米能级位于部分填充的离域带上。结合其他结构表征和显微镜数据，这些结果首次报道了金属-有机骨架中金属行为和永久孔隙率共存的现象。
