dc.description.abstractPorous organic polymers (POPs) containing donor-acceptor (D-A) moieties have recently emerged as promising electrode materials for supercapacitors due to their tunable electronic structures, controlled charge transfer capabilities, and high redox activities. In this study, a light-absorbing D-A type POP was prepared using the solvothermal method by combining a benzothiadiazole-carbazole-based donor-acceptor core with viologen-based peripheral groups. The photoelectrochemical H-type cell was constructed with a viologen-based POP photoanode and a reduced graphene oxide (rGO) cathode electrode. The specific capacitance of the supercapacitor increased from 274.8 to 383.4 F/g at 1 A/g under illumination due to the decrease in charge transfer resistance of the electrode upon exposure to light. The constructed photoelectrochemical supercapacitor retained 88% of its capacitance after 10 000 cycles under irradiation and showed an energy density of approximately 80 Wh/kg under the same conditions. These results demonstrate the potential of photo responsive D-A POPs as efficient materials for multifunctional supercapacitors.
