【摘要】 基于双氧化还原活性有机配体的二维导电金属-有机框架（2D cMOFs）是极具潜力的锂离子电池（LIBs）电极材料.然而,双配体竞争配位导致该类材料合成具有极大挑战性.本文以乙二胺为调节剂,发展了一步法合成双配体基2D c-MOF Cu₃（HHTP）（THQ）（HHTP=2,3,6,7,10,11-六羟基三亚苯,THQ=四羟基-1,4-苯醌）.所得Cu₃（HHTP）（THQ）具有良好的导电性、丰富的活性位点和优异的化学稳定性,其作为LIBs负极材料展现出高比容量、良好的倍率性能和长循环稳定性.实验结果和理论计算表明,Cu₃（HHTP）（THQ）中CuO₄活性位点和苯环单元均参与了锂存储,从而优化了储锂性能.该工作为构筑双配体基2D c-MOFs和高性能LIBs电极材料提供了新的途径.更多还原

【Abstract】 Two-dimensional conductive metal-organic frameworks（2D c-MOFs） are emerging as promising electrode materials for lithium-ion batteries（LIBs）.However,2D c-MOFs with binary redox-active organic ligands are rare and suffer from complicated synthesis procedures.Herein,a facile one-step method is developed for the synthesis of a dual-ligand-based 2D c-MOF Cu₃（HHTP）（THQ）（HHTP=2,3,6,7,10,11-hexahydroxytriphenylene,THQ=tetrahydroxy-1,4-benzoquinone） by using the ethylenediamine regulator.The resulting Cu₃（HHTP）（THQ） possesses good conductivity,abundant active sites,and excellent chemical stability.As an anode material for LIBs,Cu₃（HHTP）（THQ） exhibits high specific capacity,good rate performance,and long-term cycling stability.Comprehensive experimental studies and theoretical calculations reveal that CuO₄ units and aromatic benzene rings in Cu₃（HHTP）（THQ） are involved in lithium storage,thereby optimizing the lithium storage performance.This work provides a new way for the construction of dualligand 2D c-MOFs and high-performance LIB electrode materials.更多还原
