The structure and interactions of different (Li salt + glyme) mixtures, namely equimolar mixtures of lithium bis(trifluoromethylsulfonyl)imide, nitrate or trifluoroacetate salts combined with either triglyme or tetraglyme molecules, are probed using Molecular Dynamics simulations. structure factor functions, calculated from the MD trajectories, confirmed the presence of different amounts of lit...

Polyimides with a unique combination of properties including low color in thin films, atomic oxygen (AO), ultra-violet (UV) radiation resistance, solubility in organic solvents in the imide form, high glass transition (Tg) temperatures and high thermal stability have been prepared and characterized. The polymers were prepared by reacting a novel aromatic diamine with aromatic dianhydrides in a ...

A novel 4-amino-1,8-naphthalimide (NDI) with two different metal cation receptors connected at 4-amino or imide nitrogen positions respectively was designed and prepared. Significant internal charge transfer (ICT) as well as photoinduced electron transfer (PET) from the receptors to NDI is revealed by the shifted UV-vis absorption spectra and significant fluorescence quenching. Both Zn(2+) and ...

The antitumor drug mitindomide (NSC 284356) was shown to inhibit the decatenation activity of human and Chinese hamster ovary (CHO) topoisomerase II [DNA topoisomerase (ATP-hydrolyzing), EC 5.99.1.1]. Mitindomide did not induce the formation of topoisomerase II-DNA covalent cleavable complexes in CHO cells. These results taken together indicate that mitindomide is a catalytic/noncleavable compl...

The energy storage market relating to lithium based systems regularly grows in size and expands in terms of a portfolio of energy and power demanding applications. Thus safety focused research must more than ever accompany related technological breakthroughs regarding performance of cells, resulting in intensive research on the chemistry and materials science to design more reliable batteries. ...

The results are reported of an ab initio study of the addition of LiAlH(4) to acetonitrile and malononitrile at the MP2(full)/6-311+G* level considering the effects of electron correlation at higher levels up to QCISD(T)/6-311++G(2df,2pd) and including ether solvation. All imide (RCH(2)CH═N(-)) and enamide (RCH(-)CH═NH ↔ RCH═CHN(-)H) adducts feature strong interactions between the organic anion...

The asymmetric unit of the title compound, C56H50N6O8S2·3C6H4Cl2, contains two half-mol-ecules of the parent, A and B, which both have crystallographic inversion symmetry, together with three 2,3-di-chloro-benzene mol-ecules of solvation. Mol-ecules A and B are conformationally similar, with dihedral angles between the central naphthalenedi-imide ring and the peripheral naphthalene and benzyl r...

Abstract New experimental vapor pressures in the range 407 K to 460 and vaporization enthalpy of ionic liquids (IL) N -alkyl- -methyl-pyrrolidinium bis(fluorosulfonyl)imide have been measured using quartz crystal microbalance. The absolute enthalpies were compared with analogous pyrrolidinium-based ILs bis(trifluoromethanesulfonyl)imide anion. evaluated difference anions allowed for estimation ...
