We synthesized two hybrid organic-inorganic porous polymers (HPP) through the Heck reaction of 9,10 dibromoanthracene (A-Br) or 1,3,6,8-tetrabromopyrene (P-Br)/A-Br as co-monomers with octavinylsilsesquioxane (OVS), in order to afford OVS-A HPP and OVS-P-A HPP, respectively. The chemical structures of these two hybrid porous polymers were validated through FTIR and solid-state C and Si NMR spectroscopy. The thermal stability and porosity of these materials were measured by TGA and N adsorption/desorption analyses, demonstrating that OVS-A HPP has higher thermal stability (T: 579 °C) and surface area (433 m g) than OVS-P-A HPP (T: 377 °C and 98 m g) due to its higher cross-linking density. Furthermore, the electrochemical analysis showed that OVS-P-A HPP has a higher specific capacitance (177 F g at 0.5 A F g) when compared to OVS-A HPP (120 F g at 0.5 A F g). The electron-rich phenyl rings and Faradaic reaction between the π-conjugated network and anthracene moiety may be attributed to their excellent electrochemical performance of OVS-P-A HPP.
我们通过 9,10-二溴蒽（A-Br）或 1,3,6,8-四溴并[def]苯并[ghi]苝（P-Br）/A-Br 与辛基乙烯基倍半硅氧烷（OVS）的 Heck 反应合成了两种杂化有机-无机多孔聚合物（HPP），分别得到 OVS-A HPP 和 OVS-P-A HPP。这两种杂化多孔聚合物的化学结构通过傅里叶变换红外光谱（FTIR）和固态 C 和 Si 核磁共振光谱（NMR）得到验证。通过热重分析（TGA）和氮气吸附/脱附分析测量了这些材料的热稳定性和孔隙率，结果表明由于交联密度更高，OVS-A HPP 具有更高的热稳定性（T：579°C）和比表面积（433 m g），而 OVS-P-A HPP 的热稳定性（T：377°C）和比表面积（98 m g）较低。此外，电化学分析表明，与 OVS-A HPP（在 0.5 A F g 时为 120 F g）相比，OVS-P-A HPP 具有更高的比电容（在 0.5 A F g 时为 177 F g）。富电子的苯基环和π-共轭网络与蒽部分之间的法拉第反应可能归因于 OVS-P-A HPP 优异的电化学性能。
