| Abstract: Utilizing the rigid 6-(3-pyridyl) isophthalic acid (H2PIAD) linker, one Mn(Ⅱ)-based coordination polymer {[Mn(PIAD)(DMF)]·H2O}n (1) was prepared firstly. In order to improve the electrocatalytic activity of glucose sensing, a composite material (Ag@1) was prepared by the strategy of post synthesis of Ag nanoparticles (NPs). The electrocatalytic performance of the glassy carbon electrode (GCE) modified by Ag@1 was evaluated by chronoamperometry method at the optimized application potential, and coordination polymer 1 provided a fixed substrate for the uniform distribution of Ag NPs on its surface. Ag@1 sensor can maximize the electrocatalytic synergistic effect of the combination of Ag and 1 on glucose oxidation. The results reveal that modified GCE by Ag@1 had good performance for the detection of glucose with low detection limit (6.36 μmol·L-1), good selectivity and sensitivity (166.71 μA·L·mmol-1·cm-2). |
