摘要
By optimizing the ligands, the structure of a coordinationpolymercan be adjusted to realize the regulation and optimization of theproperties of the coordination polymer materials. Coordination polymersnot only exhibit a variety of molecular topologies but also have goodapplication prospects in adsorption, separation, catalysis, photoelectricmagnetism, and so on. Recently, coordination polymers are being wellused in precursors for electrocatalysts because of their high surfacearea and porous structure. Therefore, we selected two ligands witha similar structure in which the two coordination groups were locatedat the paracene and intersite of the benzene ring, that is, 4-(1H-1,2,4-triazol-1-yl)benzoic acid (Hbza) and 3-(1H-1,2,4-triazol-1-yl) benzoic acid (3-Hbza).We found that there are obvious differences in the crystal structurebetween Zn-bza and Zn-3bza, which is due to the different relativeposition between the carboxyl group and the triazole group leadingto the formation of different interactions, so we further studiedthe performance of their derived materials and found that the derivativematerials of the coordination polymer formed by 3-Hbza have a betterelectrocatalytic performance. This paper provides a strong supportfor the idea that a slight change in the structure of the ligand willaffect the final structure and thus the final performance.
