The magnetic field effects (MFEs) on photoinduced hydrogen abstraction reactions of benzophenone (BP) with thiophenol (PhSH) in the ionic liquids (ILs) N,N,N-trimethyl-N-propylammonium bis(trifluoromethanesulfonyl) imide (TMPA TFSI), N-methyl-N-propylpyrrolidinium bis(trifluoromethanesulfonyl) imide (P13 TFSI), and N-methyl-N-propylpiperidinium bis(trifluoromethanesulfonyl) imide (PP13 TFSI) we...
The title compound, C(30)H(22)N(2)O(4), is a derivative of the naphthalene-imide pigments that are characterized by significant overlap of the stacked mol-ecules. The mol-ecule has a centre of symmetry. Accordingly, the phenylethyl groups are arranged in a trans fashion across the skeleton. The phenyl rings are not parallel to the naphthalene-imide skeleton and are twisted in the same direction...
In the title compound, C16H11NO2·C5H9NO, the dihedral angles between the male-imide and phenyl rings are 34.7 (2) and 64.8 (2)°. In the crystal, the 2,3-di-phenyl-male-imide and 1-methyl-pyrrolidin-2-one mol-ecules form centrosymmetrical dimers via pairs of strong N-H⋯O hydrogen bonds and π-π stacking inter-actions between the two neighboring male-imide rings [centroid-centroid distance = 3.495...
In this prelude study, the high-density polyethylene/kenaf core fiber (HDPE/KCF) biocomposites without and containing hydrophobic ionic liquid, namely 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([Emim][NTf2]), were prepared via melt mixing process. The process was carried out by using an internal mixer at 150°C with a rotor speed of 60 rpm. molded into sheets through compress...
We investigate the pretilt characteristics of a nematic liquid crystal [LC] in terms of ion beam exposure conditions on the homeotropic polyimide alignment layer. The pretilt angle of LCs in the case of high-energy ion beam treatment was decreased considerably almost the same to that of the homogenous alignment layer though we used homeotropic polyimide film at first. Increasing irradiating ene...
Poly[bis(acetonitrile-κN)bis[μ3-bis(trifluoromethanesulfonyl)imido-κ4 O,O′:O′′:O′′′]dilithium]
In the title compound, [Li(2)(CF(3)SO(2)NSO(2)CF(3))(2)(CH(3)CN)(2)](n), two Li(+) cations reside on crystallographic inversion centers, each coordinated by six O atoms from bis(trifluoromethanesulfonyl)imide (TFSI(-)) anions. The third Li(+) cation on a general position is four-coordinated by two anion O atoms and two N atoms from acetonitrile mol-ecules in a tetra-hedral geometry.
A new family of low-coordinate nickel imides supported by 1,2-bis(di-tert-butylphosphino)ethane was synthesized. Oxidation of nickel(II) complexes led to the formation of both aryl- and alkyl-substituted nickel(III)-imides, and examples of both types have been isolated and fully characterized. The aryl substituent that proved most useful in stabilizing the Ni(III)-imide moiety was the bulky 2,6...
Organosilanes bearing a phosphine imide moiety were synthesized and crystallographically characterized. Reaction of the pentacoordinated hydrodiphenylsilyl derivative with water gave [2-(diphenylphosphino)phenyl]diphenylsilanol accompanied by both reduction of the phosphine imide moiety and hydrolytic oxidation of the Si-H moiety.
An iron(IV) tetrazene complex has been synthesized that is an important addition to a previously proposed catalytic aziridination cycle. It provides two key insights about the aziridination: an iron(IV) imide is formed and this imide can bind an additional ligand in the cis position.
Lithium metal batteries have attracted much attention due to their high energy density. However, the critical safety issues and chemical instability of conventional liquid electrolytes in lithium significantly limit practical application. Herein, we propose polyethylene (PE)?based gel polymer by situ polymerization, which comprise a PE skeleton, glycol bis(trifluoromethylsulfonyl)imide as well ...
