Conductive metal-organic frameworks (c-MOFs) have shown outstanding performance in energy storage and electrocatalysis. Varying the bridging metal species and the coordinating atom are versatile approaches to tune their intrinsic electronic properties in c-MOFs. Herein we report the first synthesis of the oxygen analog of M3(C6X6)2 (X = NH, S) family using Cu(II) and hexahydroxybenzene (HHB), namely Cu-HHB [Cu3(C6O6)2], through a kinetically controlled approach with a competing coordination reagent. We also successfully demonstrate an economical synthetic approach using tetrahydroxyquinone as the starting material. Cu-HHB was found to have a partially eclipsed packing between adjacent 2D layers and a bandgap of approximately 1 eV. The addition of Cu-HHB to the family of synthetically realized M3(C6X6)2 c-MOFs will enable greater understanding of the influence of the organic linkers and metals, and further broadens the range of applications for these materials.

二维半导电铜六羟基苯金属-有机骨架的合成路线

导电金属有机骨架（c-MOFs）在储能和电催化方面表现出优异的性能。改变桥接金属种类和配位原子是在 c-MOF 中调节其固有电子特性的通用方法。在此，我们报告了使用 Cu(II) 和六羟基苯 (HHB) 首次合成 M3(C6X6)2 (X = NH, S) 族的氧类似物，即 Cu-HHB [Cu3(C6O6)2]，通过动力学使用竞争配位试剂的受控方法。我们还成功地展示了一种使用四羟基醌作为起始材料的经济合成方法。发现 Cu-HHB 在相邻 2D 层之间具有部分重叠的堆积和大约 1 eV 的带隙。
