Abstract
A conjugated porous organic polymer (SMCOP-4) with imine linkage was rationally designed and synthesized by an imine condensation reaction. The π-conjugated network structure of SMCOP-4 facilitates electron mobility, enhancing electrochemical activity. The bifunctional electrocatalyst SMCOP-4 shows superior performance for HER and OER with a low overpotential of 127 mV and 295 mV, respectively, at 10 mA cm-2 current density and with small Tafel slopes in alkaline electrolytes. Along with the low overpotential values, the electrocatalyst is highly stable at electrochemical conditions.
