A new type of imidazolium salt-modified porous hypercrosslinked polymer (BET surface area up to 926 m2 g-1) was reported. These porous materials exhibited good CO2 capture capacities (14.5 wt%) and catalytic activities for the conversion of CO2 into various cyclic carbonates under metal-free conditions. The synergistic effect of CO2 capture and conversion was observed.

Imidazolium functionality has played a prominent role in research on anion exchange membranes for use in alkaline electrochemical devices. Base stability and degradation of these materials has been much studied, but in many instances, product pathways have not been thoroughly delineated. We report an NMR study of base-induced decomposition products from three benzylimidazolium salts bearing varying extents of methyl substitution on the imidazolium ring. The major products are consistent with a hydrolytic ring fragmentation pathway as the principal mode of decomposition. We observe several new products not previously reported in the literature on imidazolium salt degradation, including benzilic acid rearrangement products formally derived from intermediate 1,2-dicarbonyl compounds or their equivalents. However, the overall reactions are complex, the yields of observed products do not account for all consumed starting materials, and mechanistic ambiguities remain.
PHOTOBASE GENERATOR
-
Paragraph 0109, (2016/02/03)
There is provided a photobase generator and a photosensitive resin composition containing the photobase generator. The photobase generator includes an ammonium salt represented by general formula (1). In formula (1), R1 to R4 independently represent an alkyl group having 1 to 18 carbon atoms or Ar, wherein at least one of R1 to R4 represents Ar; Ar represents an aryl group having 6 to 14 carbon atoms (excluding carbon atoms contained in a substituent as mentioned below), wherein some of hydrogen atoms in the aryl group may be independently substituted by an alkyl group having 1 to 18 carbon atoms or the like; Y+ represents an ammonio group represented by general formula (2) or (3); and E represents a hydrogen atom or a group represented by general formula (5).
