“…Water contaminants can be divided into two different categories: inorganic and organic. Major organic water contaminants include dyes, bisphenols, aniline, pesticides, and perchlorinated biphenyls. Moreover, emerging organic contaminants, including nonsteroidal anti‐inflammatory drugs, perfluorinated alkyls, biotoxins, and flame retardants are ubiquitous in the aquatic environment .…”

The demand for practical and cost-effective environmental treatment and energy storage materials is exploding. Porous polymeric and carbonaceous materials have attracted tremendous interest on account of their welldeveloped porosity and tunable surface chemistry. Functionalization of pore structures further enhances their properties for environmental treatment and energy storage. Herein, the procedures for functionalization of porous structures are introduced, including predesign and postsynthetic strategies. Subsequently, the important advancements of emerging porous polymers for environmental treatment in sorption (e.g., organic micropollutant adsorption, heavy metal ion removal, radionuclide extraction, and oil absorption) and membrane separation (e.g., aqueous micropollutant separation, organic solvent nanofiltration, desalination and pervaporation), as well as for energy storage ranging from the electrodes and separators of batteries to supercapacitor electrodes are highlighted. Moreover, given the combined merits of high intrinsic conductivity, porosity, and physicochemical stability, novel polymer-based porous carbons for energy storage are also highlighted. Key functionalization chemistry for each application is discussed and an in-depth understanding of the structure-property relationships of these functional porous materials is provided. Finally, the challenges and perspectives of emerging functional porous polymeric and carbonaceous materials for environmental treatment and energy storage are proposed.

“…Scheme 1 A , B show the synthetic methods for the preparation of TPE and DPT monomers. The TPE monomer was firstly prepared through the reaction of benzophenone with zinc in the presence of TiCl 4 [ 56 , 57 ], while the DPT monomer was synthesized by the reaction of benzil with 4-(diphenylamino)benzaldehyde (TPA-CHO) and ammonium acetate in acetic acid at 90 °C [ 50 ]. Scheme 2 represented the schematic method for preparing the two different HPPs—TPE and DPT HPPs—via a Friedel–Crafts reaction of TPE and DPT with 1,4-bis(chloromethyl)benzene in the presence of anhydrous FeCl 3 as a catalysis at 60 °C for 24 h. After the reactions were completed, the crude materials were washed several times with MeOH, THF, acetone, DCM, and DMF to remove any excess from the unreacted FeCl 3 and monomers.…”

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.

“…The sorption isotherm of P2 – P4 exhibited a combination of type I and IV nitrogen sorption isotherms according to the IUPAC classification [36]. The hysteresis between adsorption and desorption of P2 – P4 indicates that the polymers contain mesopores [37]. There is no sharp rise at high relative pressures ( P / P 0 > 0.9) of P1 – P5 , which means that scarcely macropores exist in the networks [38].…”

To systematically explore the effects of the synthesis conditions on the porosity of hyper-cross-linked polymers (HCPs), a series of 9-phenylcarbazole (9-PCz) HCPs (P1–P11) has been made by changing the molar ratio of cross-linker to monomer, the reaction temperature T 1, the used amount of catalyst and the concentration of reactants. Fourier transform infrared spectroscopy was utilized to characterize the structure of the obtained polymers. The TG analysis of the HCPs showed good thermal stability. More importantly, a comparative study on the porosity revealed that: the molar ratio of cross-linker to monomer was the main influence factor of the BET specific surface area. Increasing the reaction temperature T 1 or changing the used amount of catalyst could improve the total pore volume greatly but sacrificed a part of the BET specific surface area. Fortunately changing the concentration of reactants could remedy this situation. Slightly changing the concentration of reactants could simultaneously obtain a high surface area and a high total pore volume. The BET specific surface areas of P3 was up to 769 m2 g−1 with narrow pore size distribution and the CO2 adsorption capacity of P11 was up to 52.4 cm3 g−1 (273 K/1.00 bar).
