ABSTRACT The development of low‐cost, high‐efficiency, stable, and structurally adjustable electrocatalysts for hydrogen evolution reaction (HER) is great significance energy conversion. In this study, two new Cu(I) coordination polymers (CPs), formulated as {[Cu(L 1 )](PF 6 )·CH 2 Cl } n ( ) {[Cu (L 1.5 (PPh 3 = 1,3‐bis[1‐(pyridin‐3‐ylmethyl) ‐1H‐benzimidazol‐2‐yl]propane, L 1,4‐bis[1‐(3‐pyridylmethyl)‐1H‐benzimidazol‐2‐yl]butane), were synthesized by interfacial diffusion method characterized single‐crystal x‐ray diffraction IR UV–Vis spectra. Structural analysis shows that the CP‐ a one‐dimensional chain structure, whereas two‐dimensional layered which due to different modes ligands (bridging chelation) (bridging). electrocatalytic activity HER CPs was studied preparing modified glassy carbon electrodes (CP‐ /GCE /GCE).
