Triptycene-Based Hyper-Cross-Linked Polymer Sponge for Gas Storage and Water Treatment

Abstract

Cost-effective adsorbents for water treatment is easy available through one-pot Friedel−Crafts reaction of triptycene. With hierarchical porous structure, high surface area, high thermal stability, and excellent adsorption capacities for organic solvents and dyes, the triptycene-based hyper-cross-linked polymer sponge (THPS) may be ideal adsorbents for a wide range of large-scale applications in water purification and treatment.

Ferrocene‐Functionalized Silsesquioxane‐Based Porous Polymer for Efficient Removal of Dyes and Heavy Metal Ions

“…Although CR is an anionic dye, it exhibited the maximum absorption capacity, suggesting the absorption of Fc‐HPP for dyes mainly depends on the size of the dye. The larger molecules could enter and bind in the micropores, whereas small‐sized molecules could easily enter into and out of pores so that Fc‐HPP preferred to absorb large‐sized dyes molecules . Compared with CV, the carboxyl group and one quinone ring in RB could result in relatively weaker electrostatic interaction with Fc‐HPP .…”

“…Furthermore, the color of the solution turned from dark red to pale red, then to nearly colorless, while the Fc‐HPP power became rufescent (as shown in the inset of Figure ). Meanwhile, pseudo‐first‐order and pseudo‐second‐order models served to simulate the absorption performance and the results suggested that the pseudo‐second‐order kinetic model was more favorable to explain the absorption process by comparing the value of R 2 . The fitted curves and correlative kinetic parameters are listed in Figure S7 and Table S3 in the Supporting Information, respectively.…”

Swellable functional hypercrosslinked polymer networks for the uptake of chemical warfare agents

“…42,43 Knitting of the triptycene monomer can produce HCPs which show high adsorption for solvents including DMSO, toluene, and ethyl acetate, with a 30 times increase in the mass of the polymer observed for adsorption of chloroform. 44 Functionalised β-cyclodextrins have been used to extract phenol and its derivatives from aqueous solutions. 45 Gold nanoparticles have also been incorporated into hypercrosslinked β-cyclodextrin to facilitate catalytic reactions on the adsorbed materials.…”

Porphyrin‐based polymer‐supported palladium as an excellent and recyclable catalyst for Suzuki–Miyaura coupling reaction in water

“…N 2 adsorption–desorption isotherm of Pd/KAPs(DCM‐TPP) at 77 K displayed a typical type І curve along with a large adsorption at low pressure ( P / P 0 < 0.1), which are suggestive of the coexistence of micropores and mesopores in the framework (Figure ) . The Brunauer–Emmett–Teller surface area was found to be 1357 m 2 g −1 .…”
