Two-dimensional (2D) electrically conductive metal-organic frameworks (MOFs) have emerged as viable candidates for active electrode materials in supercapacitors due to their high electrical conductivity, specific surface area, and intrinsic redox-active sites. Despite promising electrochemical performance, pseudocapacitive behavior via fast reversible charge transfer reactions remains yet be fully exploited. Here, we investigate the energy storage mechanism of Cu

Redox-active porous organic polymers (POPs) demonstrate significant potential in supercapacitors. However, their intrinsic low electrical conductivity and stacking tendencies often lead to utilization rates of redox-active sites within structural units. Herein, polyimide POPs (donated as PMTA) are synthesized situ on multi-walled carbon nanotubes (MWCNTs) from tetramino-benzoquinone (TABQ) 1,4,5,8-naphthalene tetracarboxylic dianhydride (PMDA) monomers. The strong π–π interactions drive the PMTA MWCNTs together form a PMTA/MWCNT composite. With assistance MWCNTs, issue well addressed, leading obvious activation enhanced groups POPs. then achieves high capacitance 375.2 F g−1 at 1 A compared pristine (5.7 g−1) excellent cycling stability 89.7% after 8000 cycles 5 g−1. Cyclic voltammetry (CV) Fourier-Transform Infrared (FT-IR) results reveal that electrode reactions involve reversible evolution carbonyl groups, which activated provide rich pseudocapacitance. Asymmetric supercapacitors (ASCs) assembled with PMTA/MWCNTs (AC) offer energy density 15.4 Wh kg−1 980.4 W maintain retention 125% 10,000 g−1, indicating good for practical applications.

Incorporation of redox-active centers in metal–organic coordination polymers has gained significant interest due to their tunable electronic properties. To this end, we have electropolymerized a thin film manganese ions coordinated with dimercapto thiadiazole metallo-organic polymer (poly-MnDMcT) containing Mn3+/4+ and S–2/–1 redox couples. The poly-MnDMcT demonstrated mixed charge storage mechanism capacitive diffusion-controlled contributions coexisting.
