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...

One of the most prominent hole-transporting material (HTM) for hybrid perovskite solar cells has been 2,2?,7,7?-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9?-spirobifluorene (spiro-OMeTAD), which is commonly doped with metal bis(trifluoromethylsulfonyl)imide (M(TFSI)n) salts that contribute to generating active radical cation HTM species. The underlying role cation, however, remains elusive. Here...

Metal halide perovskites have received much attention for their application in light-emitting diodes (LEDs) and solar cells the past several years. Among them, 2D quasi-2D perovskite with organic long-chain cations introduced drawn significant attention. However, while improving wet thermal stability, as grain size becomes smaller, more defects at boundary surface, resulting increase of non-rad...

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.

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 ...
