We investigated the performance that is improved in various applications through molecular structural alterations. Specifically, we emphasized importance of controlling branching densities organic moieties as a useful tactic for varying surface area and porosity hybrid porous organic/inorganic polymers (HPPs), which include octavinylsilsesquioxane (OVS) units. This study shows adjusting could greatly enhance energy storage hydrogen production. The two-branched chemical structure (4,7-dibromo-2,1,3-benzothiadiazole, BT-Br2) four-branched compound (1,1,2,2-tetrakis(4-bromophenyl)ethylene, TPE-Br4) are individually reacted with OVS 1,3,6,8-tetrabromopyrene (Py-Br4) twice to prepare HPPs. These materials high or low cross-linking density, well small large areas, synthesized by this dual reaction, also produces HPPs different densities. Based on Brunauer–Emmett–Teller calculations, OVS-Py-BT HPP has more than 4.5 times larger OVS-Py-TPE material. Remarkably, exhibited exceptional results supercapacitor applications, specific capacitance values 248 54 F/g HPPs, respectively, determined galvanostatic charge–discharge. significantly outperformed photocatalytic evolution. evident from their respective evolution rates: 1348 μmol g–1 h–1 much lower 11.3 HPP.
