Abstract: Photoinduced transition-metal- and photosensitizer-free cross-coupling of aryl halides (including Ar-Cl, Ar-Br, and Ar-I) with H-phosphonates (including dialkyl phosphonates and diarylphosphine oxides) is reported. Various functional groups were tolerated, including ester, methoxy, dimethoxy, alkyl, phenyl, trifluoromethyl,… read more here.

DOI: 10.7567/1882-0786/ab45e2
Abstract: We proposed solvent-free cross-linked ion gel polymer as a high-κ gate dielectric composed with polyurethane terminated with acrylate functional group and ionic liquids (1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide) through ultra violet curing (UV-cured IL-PU). Free-standing UV-cured IL-PUs were… read more here.
