Multifunctional Hypercrosslinked Porous Organic Polymers Based on Tetraphenylethene and Triphenylamine Derivatives for High-Performance Dye Adsorption and Supercapacitor

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 FeCl3 as a catalyst. Our porous materials exhibited high BET surface areas (up to 1000 m2 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.

Multifunctional Polyhedral Oligomeric Silsesquioxane (POSS) Based Hybrid Porous Materials for CO2 Uptake and Iodine Adsorption

“…TPE was prepared according to our previous study [ 7 , 13 ]. Benzophenone (3.00 g, 16.20 mmol), zinc (3.91 g, 59.4 mmol), and dry THF (100 mL) were stirred and kept at 0 °C for 30 min.…”

“…The preparation of porous organic polymers (POPs) has become a hot topic in the academic and industry fields due to their interesting features, such as high physicochemical stability, porous character, low density, facile preparation, low regeneration energy, and good thermal and chemical stabilities [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Porous organic polymers have been applied in different applications such as light harvesting, chemical sensors, catalysis, iodine uptake, H 2 production from water, water treatment, optoelectronic devices, carbon dioxide reduction, nanofiltration, enantioseparation, energy storage, gas separation, and adsorption [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ].…”

Meso/Microporous Carbons from Conjugated Hyper-Crosslinked Polymers Based on Tetraphenylethene for High-Performance CO2 Capture and Supercapacitor

“…TPE: Tetraphenylethene (TPE) monomer was successfully synthesized according to our previous report [ 47 , 50 ]. FTIR (KBr, cm −1 , Figure S1 ): 3047 (aromatic C–H stretching), 1602 (C=C stretching).…”

“…Hyper-crosslinked polymers (HCPs) [ 28 , 29 , 30 , 31 , 32 , 33 ], covalent organic frameworks (COF) [ 34 , 35 , 36 , 37 , 38 , 39 , 40 ], conjugated microporous polymers (CMPs) [ 41 , 42 , 43 , 44 , 45 ], and polymers of intrinsic microporosity (PIMs) are considered as types of microporous organic polymers (MOPs) [ 46 , 47 , 48 , 49 ]. As mentioned above, HCPs are considered as a kind of porous material that can be easily synthesized through the Friedel–Crafts alkylation reaction of rigid aromatic monomers with an external crosslinker such as formaldehyde dimethyl acetal, 1,3,5-trichlorotriazine, and 1,4-bis(chloromethyl)benzene [ 50 , 51 , 52 ]. Compared with other microporous material such as activated carbon, HCPs can be synthesized by low-cost monomers, catalysts, and suitable reaction conditions [ 53 , 54 ].…”

“…Compared with other microporous material such as activated carbon, HCPs can be synthesized by low-cost monomers, catalysts, and suitable reaction conditions [ 53 , 54 ]. In addition, HCPs materials feature easy functionalization, good chemical and thermal properties, microporous nature, and large surface areas [ 50 , 51 , 52 , 53 , 54 ]. Nowadays, the preparation of porous carbon materials has attracted much attention due to their interesting properties such as excellent electrical conductivity, high surface areas and high pore volumes, and good chemical, thermal, and mechanical stabilities [ 55 , 56 , 57 , 58 , 59 ].…”
