Poly(ionic liquid)s with unique adsorption-swelling ability to epoxides are facilely synthesized via free radical polymerization in water, serving as highly efficient heterogeneous catalysts for atmospheric CO 2 cycloaddition under mild conditions.
Acidic poly(ionic liquid)s (PILs) with swelling ability were synthesized by free radical copolymerization of N-vinylimidazolium ionic liquids, divinylbenzene (DVB) and sodium acrylate (NaAA), further acidification sulfuric acid. The acidic PILs was greatly affected cross-linker content chain length 3-alkyl-substituents on imidazolium. Cross-linked network structures could be observed from the cryogenic scanning electron microscopy (cryo-SEM) images swollen in formic state exhibited excellent...
Water enrichment ability increased the catalytic efficiency of PIL microreactors in hydrolysis EC.
A series of oil/water separation membranes with tunable surface wettability based on poly(ionic liquid)s (PILs) were prepared via a facile one-step photopolymerization N-vinylimidazolium ionic liquids and divinylbenzene meshes. The PIL-based (PILMs) was adjusted by the structures PILs, specifically alkyl chain length imidazolium (butyl octyl) anion species (acrylic anion, Br–, PF6–). Tunability resulted in hydrophilic or hydrophobic property PILMs. poly(1-vinyl-3-butylimidazolium...
A kind of oil/water separation membrane, combining poly(ionic liquid) (PIL) and three-dimensional (3D) wire mesh, was designed prepared via one-step photopolymerization an ionic liquid monomer 1,8-triethylene glycoldiyl-3,3'-divinylimidazolium dibromide ([DVIm-(EG)3]Br2) with acrylic acid in the mesh.

The synthesis of dimethyl carbonate (DMC) via transesterification ethylene (EC) and methanol (MeOH) was an environmental practical strategy. Herein, poly(ionic liquid)s (PILs) with swelling abilities were synthesized by free radical copolymerization N-vinylimidazolium ionic liquids, sodium 4-vinylbenzoate cross-linker 1,8-triethylene glycoldiyl-3,3ʹ-divinylimidazolium bromide ([(EG)3-DVIm]Br2). PILs in various solvents measured, could swell (MeOH). ability MeOH be modulated changing the...
A selective procedure for the synthesis of 5‐substituted N ‐aryloxazolidinones by coupling epoxides with arylcarbamates catalyzed ionic liquids has been developed. The effects reaction time, reactant molar ratio, amount catalyst, and temperature were investigated. Under optimal conditions, BmimOAc exhibited efficient catalytic activity compared other leading to formation in excellent yields. In addition, chiral oxazolidinones synthesized this good‐to‐excellent yields enantiomeric excesses...
InGaN p-i-n homojunction (HOJ) and heterojunction (HEJ) solar cells (SCs) with similar width of depletion region are investigated. Through comparison both the material property device performance, it is demonstrated that HEJ exhibits much better results than HOJ, indicating preferred for fabrication SCs. Some suggestions proposed development SCs in future.
Heterogeneous catalysts usually show much lower catalytic activities than homogeneous due to insufficient dispersion and contact of catalytically active sites reactants. Efforts have been made solve this problem during past decades. Herein, we synthesized a series poly (ionic liquid)s (PILs), which are well swelled in ethylene carbonate (EC), by polymerization N-vinylimidazolium ionic liquid monomers with divinylbenzene (DVB). The structure, morphology swelling property the PILs were...

Abstract Urea‐functionalized poly(ionic liquid)s (PILs) were synthesized through polymerization of urea tethered imidazolium ionic liquid monomers (urea‐IL) with sodium acrylate, and N,N′‐methylenebisacrylamide (MBA) as a crosslinker. Close‐packed interconnected pores (1–4 ) under swollen state could be observed from the cryogenic scanning electron microscopy (cryo‐SEM) images. The promising catalytic activity PILs was illustrated for transesterification reaction ethylene carbonate methanol....
