We successfully prepared two different classes of hypercrosslinked porous organic polymers (HPPs)-the tetraphenylethene (TPE) and (4-(5,6-Diphenyl-1H-Benzimidazol-2-yl)-triphenylamine (DPT) HPPs-through the Friedel-Crafts polymerization of tetraphenylethene and 4-(5,6-diphenyl-1H-benzimidazol-2-yl)-triphenylamine, respectively, with 1,4-bis(chloromethyl)benzene (Ph-2Cl) in the presence of anhydrous FeCl as a catalyst. Our porous materials exhibited high BET surface areas (up to 1000 m g) and good thermal stabilities. According to electrochemical and dyes adsorption applications, the as-prepared DPT-HPP exhibited a high specific capacitance of 110 F g at a current density of 0.5 A g, with an excellent cycling stability of over 2000 times at 10 A g. In addition, DPT-HPP showed a high adsorption capacity up to 256.40 mg g for the removal of RhB dye from water.

我们通过分别使四苯乙烯和4-(5,6-二苯基-1H-苯并咪唑-2-基)-三苯胺与1,4-双(氯甲基)苯(Ph-2Cl)在无水FeCl作为催化剂存在的条件下进行傅克聚合反应，成功制备了两类不同的超交联多孔有机聚合物（HPPs）——四苯乙烯（TPE）和4-(5,6-二苯基-1H-苯并咪唑-2-基)-三苯胺（DPT）HPPs。我们的多孔材料表现出高比表面积（高达1000 m²/g）和良好的热稳定性。根据电化学和染料吸附应用，所制备的DPT-HPP在电流密度为0.5 A/g时表现出110 F/g的高比电容，在10 A/g下具有超过2000次的优异循环稳定性。此外，DPT-HPP对从水中去除罗丹明B染料显示出高达256.40 mg/g的高吸附容量。
