摘      要：A new three-dimensional coordination polymer composed of Cu2+ centres and semiquinoid linkers (dhbq(2-)) was synthesized which was composed by two independent, enantiomeric, interpenetrated [Cu-2(dhbq)(3)](2-) networks with (10,3)-a topology. The compound has good water stability and typical behaviors of semiconductor, whose conductivity increases along with raising temperature. The chemiresistive humidity sensor made from this material shows good properties including linear sensitivity, high response, fast response and recovery, and particularly narrow hysteresis during humidity adsorption and desorption.
