▎ 摘　　要

A series of conductive metal-organic frameworks (M-CATs) were synthesized using 2,3,6,7,10,11-hexahydroxytriphenylas a ligand following a solvothermal method, and the Cu-CAT system exhibiting the best performance was identified. Conductive Cu-CAT-anchored reduction graphene oxide composites (Cu-CAT@rGO) were prepared following a hydrothermal method. The microstructures of the systems were further characterized using X-ray diffraction, scanning electron microscopy, energy dispersion spectroscopy, and transmission electron microscopy techniques. The drip-casting membrane method was used for the fabrication of a novel electrochemical sensor based on the conductive Cu-CAT-anchored rGO (Cu-CAT@rGO/GCE). The electrochemical performance of Cu-CAT@rGO/GCE was studied using electrochemical impedance spectroscopy and cyclic voltammetry techniques. The differential pulse voltammetry technique was used for electrochemical sensing to detect the content of bisphenol A (BPA) in beverage bottles. An excellent linear detection range (0.05-100 mu mol L-1) and a low detection limit (4.9 nmol L-1; based on S/N = 3) were recorded. Therefore, this method can potentially be used to develop a new route for the detection of BPA. [GRAPHICS]
