H2O2 as green and environmentally benign reagent for the oxidation of TMS ethers, THP ethers, and alcohols in the presence of {[K.18-Crown-6]Br3}n

Green Chemistry Letters and Reviews, 2017
In the presence of {[K.18-Crown-6]Br3}n, a unique tribromide reagent, trimethylsilyl (TMS) ethers, tetrahydropyranyl (THP) ethers, and alcohols were oxidized to their corresponding aldehydes and ketones in H2O2.

Miscibility of poly(ether ether ketone)/poly(ether diphenyl ether ketone) blends

Polymer, 1996
Poly(ether ether ketone) and poly(ether diphenyl ether ketone) homopolymers are prepared by nucleophilic substitution routes. Miscibility of PEEK/PEDEK blends has been studied by wide-angle X-ray diffraction (WAXD) and differential scanning calorimetry (d.s.c.).

Short and efficient synthesis of thiol group functionalized crown ethers

, 2007
A synthesis of thiol group functionalized crown ethers is reported. The reaction is accomplished by the direct chlorosulfonation of simple crown ethers with chlorosulfonic acid and the reduction of the sulfonyl chloride moiety with LiAlH4 in two steps ...

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Unusual facet and co-catalyst effects in TiO2-based photocatalytic coupling of methane

Nature Communications
Photocatalytic coupling of methane to ethane and ethylene (C2 compounds) offers a promising approach to utilizing the abundant methane resource. However, the state-of-the-art photocatalysts usually suffer from very limited C2 formation rates.
