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 pi-conjugated EC-MOF containing copper units with mixed trigonal ligands was developed: Cu-3(HHTP)(THQ) (HHTP=2,3,6,7,10,11-hexahydrotriphenylene, THQ=tetrahydroxy-1,4-quinone). The modulated conductivity (sigma approximate to 2.53x10(-5) S cm(-1) with an activation energy of 0.30 eV) and high porosity (ca. 441.2 m(2) g(-1)) of the Cu-3(HHTP)(THQ) semiconductive nanowires provided an appropriate resistance baseline and highly accessible areas for the development of an excellent chemiresistive gas sensor.
