One-pot construction of nitrogen-rich polymeric ionic porous networks for effective CO₂ capture and fixation

Abstract

Facile preparation of ionic porous networks (IPNs) with a large and permanent porosity is highly desirable for CO2 capture and transformation, which remains a challenge. Here we report a one-pot...

A Photosensitive Cationic Macrocycle Based on Triphenylamine as Photocatalysts for Selective Photooxidation of Phosphines, Styrenes, and Hydroazobenzenes

“…The target product was obtained in the form of a red solid and was analyzed by using 1 H NMR and 13 C NMR techniques (Figures S1–S3), which exhibited excellent solubility in water. In addition, the quantitative determination of Cl – was identified in its chloride form via anion exchange experiment (AEC), , which was measured to be 3.06 mmol/g. This value aligns with the expected chloride content of TPPB.…”

Pyrazolium ionic liquids with multiple active sites immobilized on mesoporous MCM-41 for chemical fixation of CO2 under mild conditions

“…Various porous materials have been reported for immobilizing ionic liquids to facilitate their separation and recovery. These materials include metal-organic frameworks (MOFs), 9,10 graphitic carbon nitride (g-C 3 N 4 ), 11,12 porous organic polymers, [13][14][15][16] nitrogen-rich polymeric ionic networks (IPNs-CSUs), 17 silica (SiO 2 ), 18,19 aluminosilicate Zeolite Socony Mobil-5 (ZSM-5), 20 and mesoporous silica such as Santa Barbara Amorphous-15 (SBA-15) 21 and Mobil Composition of Matter number 41 (MCM-41). 22 In particular, MCM-41, as an important mesoporous material, has attracted extensive attention in supporting ILs due to its ordered hexagonal array of uniform pores, enabling high surface area and tunable pore sizes.…”
