摘　　要：金属有机骨架(MOFs)是由金属离子或簇与有机配体以配位键组装而成的晶态多孔材料,其高的孔隙率及功能可设计性使其广泛应用于各种领域。然而,传统MOFs多数电导率非常低,这严重制约了其在电学相关领域的发展。近年来,导电金属有机骨架尤其是二维导电金属有机骨架(2D ECMOFs)材料因其结构中独特的π-π堆积及π-d共轭作用而呈现出半导体甚至类金属的电子输运性质而受到广泛关注,已在传感器、电子器件、电催化、电池和超级电容器等电学和能源相关领域展现出潜在的应用价值。本文将从2D ECMOFs的导电机理、结构、合成方法及应用等方面对近几年该领域的重要进展进行综述,并对其未来发展的挑战和机遇提出展望。Metal-organic frameworks(MOFs) are a class of crystalline porous materials formed by self-assembly of metal ions or clusters and organic ligands through coordination bonds. Due to the high porosity and functional designability, MOFs have found wide applications of which make them widely used in various fields. However, most traditional MOFs have poor conductivity, which severely restricts their development in electrical related fields. In recent years, electrically conductive MOFs, especially two dimensional electrically conductive MOFs(2 D ECMOFs), have attracted a great deal of research attention due to their semiconducting or metallic properties closely-related to their unique π-π stacking and π-d conjugation structures, which have great application potentials in electrical and energy related fields such as sensors, electronics, electrocatalysts, batteries, and supercapacitors. In this review, the recent progress in conducting mechanisms, structures, synthesis strategies and applications of 2 D ECMOFs are summarized and highlighted. Furthermore, future challenges and opportunities based on the current research status are prospected.
