Electrically conductive metal–organic frameworks (MOFs) provide a rare example of porous materials that can efficiently transport electrical current, a combination that is favorable for a variety of technological applications. The vast majority of such MOFs are highly anisotropic in both their structures and properties: Only two electrically conductive MOFs reported to date exhibit cubic structures that enable isotropic charge transport. Here we report a new family of intrinsically porous frameworks made from rare-earth nitrates and hexahydroxytriphenylene. The materials feature a novel hexanuclear secondary building unit and form cubic, porous, and intrinsically conductive structures, with electrical conductivities reaching 10–5 S/cm and surface areas of up to 780 m2/g. By expanding the list of MOFs with isotropic charge transport, these results will help us to improve our understanding of design strategies for porous electronic materials.

多孔立方稀土邻苯二酚盐的电导率

导电金属有机骨架（MOF）提供了一个罕见的多孔材料例子，它可以有效地传输电流，这种组合有利于各种技术应用。绝大多数此类 MOF 在其结构和性质上都具有高度各向异性：迄今为止报道的只有两种导电 MOF 表现出能够实现各向同性电荷传输的立方结构。在这里，我们报告了由稀土硝酸盐和六羟基苯并菲制成的一系列新的固有多孔框架。该材料具有新颖的六核二次构建单元，形成立方、多孔和固有导电结构，电导率达到 10-5 S/cm，表面积高达 780 m2/g。通过扩展具有各向同性电荷传输的 MOF 列表，
