Single-ligand-based electronically conductive porous coordination polymers/metal-organic frameworks (EC-PCPs/MOFs) fail to meet the requirements of numerous electronic applications owing to their limited tunability in terms of both conductivity and topology. In this study, a new 2D π-conjugated EC-MOF containing copper units with mixed trigonal ligands was developed: Cu (HHTP)(THQ) (HHTP=2,3,6,7,10,11-hexahydrotriphenylene, THQ=tetrahydroxy-1,4-quinone). The modulated conductivity (σ≈2.53×10 S cm with an activation energy of 0.30 eV) and high porosity (ca. 441.2 m g ) of the Cu (HHTP)(THQ) semiconductive nanowires provided an appropriate resistance baseline and highly accessible areas for the development of an excellent chemiresistive gas sensor.
基于单配体的导电多孔配位聚合物/金属有机框架（EC-PCPs/MOFs）由于其在导电性和拓扑结构方面的可调性有限，无法满足众多电子应用的需求。在本研究中，开发了一种新的二维π共轭EC-MOF，其包含具有混合三角配体的铜单元：Cu (HHTP)(THQ)（HHTP = 2,3,6,7,10,11-六氢三亚苯，THQ = 四羟基-1,4-醌）。Cu (HHTP)(THQ)半导体纳米线的调制电导率（σ≈2.53×10 S cm，活化能为0.30 eV）和高孔隙率（约441.2 m g ）为开发优异的化学电阻式气体传感器提供了合适的电阻基线和高度可及的区域。
