Abstract
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(3) as a catalyst. Our porous materials exhibited high BET surface areas (up to 1000 m(2) g(-1)) 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(-1) at a current density of 0.5 A g(-1), with an excellent cycling stability of over 2000 times at 10 A g(-1). In addition, DPT-HPP showed a high adsorption capacity up to 256.40 mg g(-1) for the removal of RhB dye from water.
