Supercapacitors (SCs), with their exceptional properties, offer a promising solution to the ongoing energy crisis, addressing growing demand for high-energy storage devices. Polymeric organic porous materials (POIPs) exhibit various sizes, precisely controlled porosities, lightweight nature, extensive surface areas, impressive intrinsic porosity, attractive chemistry, outstanding stability, and customizable structures functionalities. These features collectively render POIPs as cost-effective material applications in storage. This study successfully synthesized an octavinylsilsesquioxane (OVS)-FO-POIP through Heck coupling reaction between OVS 2,7-dibromo-9H-fluoren-9-one (DBFO). Confirmation of OVS-FO-POIP's chemical structure was achieved using solid-state 13C 29Si NMR Fourier transform infrared analyses. Subsequently, carbonization KOH activation at 900 °C yielded carbon material, denoted OVS-FO-POIP-900. Microporous characteristics were evidenced by specific area (SBET) values 264 m2 g–1 OVS-FO-POIP 387 OVS-FO-POIP-900 corresponding pore diameters 1.90 1.59 nm, respectively. Notably, demonstrated improved particular capacitance 776 F compared that (271 g–1) current density 1 A g–1, addition retention up 79% after 6000 cycles. The heightened enhances probability electrochemical reactions, thereby elevating levels. To delve deeper into performance, symmetric devices constructed both OVS-FO-POIP-900, exhibiting capacitances 167 268 Remarkably, performance these assessments, suggesting its potential suitability SC applications.
