In this paper, we investigate via experimental and simulation techniques the transport properties, in terms of total ionic conductivity and ion diffusion coefficients, of ionic liquids doped with lithium salts. They are composed of two anions, bis(fluorosulfonyl)imide (FSI) and bis(trifluoromethanesulfonyl)imide (TFSI), and two cations, N-ethyl-N-methylimidazolium (emim) and lithium ions. The c...

Phthalic, maleic and succinic anhydrides have been reacted with aromatic amines to obtain the corresponding monoacid monoamides. The latter have been each transformed into the corresponding cyclic imide derivatives by treating with SOCl2. Alternatively, anhydrides have been reacted with methanolic KOH to obtain monomethyl ester derivatives which on reaction with aromatic amines in the presence ...

In this paper, new bolaform cholesteryl imide derivatives with different spacers were designed and synthesized. Their gelation behaviors in 23 solvents were investigated, and some of them were found to be low molecular mass organic gelators. The experimental results indicated that these as-formed organogels can be regulated by changing the flexible/rigid segments in spacers and organic solvents...

In this study we investigated the chemical-physical properties of mixtures containing the protic ionic liquid (PIL) N-butyl-pyrrolidinium bis(trifluoromethanesulfonyl)imide (PYRH4TFSI), propylene carbonate (PC) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in view of their use as electrolytes for lithium-ion batteries (LIBs). We showed that these electrolytic solutions might display c...

Pyrene labelled Zn(2+)-cyclen 1 and bis-Zn(2+)-bis-cyclen 2 complexes were synthesized. The reversible coordination at physiological pH of Zn(2+)-cyclens to phosphate anions and to imide moieties, as present in thymine and uracil nucleotides, is well known. In the presence of analytes bearing a phosphate and an imide or two phosphate groups the formation of a ternary complex consisting of two p...

The unusual trinuclear Au(III) oxide title complex, [Au(3)Cl(6)O(C(21)H(24)N(2))(3)](C(2)F(6)NO(4)S(2))·2[Ag(C(2)F(6)NO(4)S(2))], is the side product of the reaction of [1,3-bis-(1,3,5-trimethyl-phen-yl)imidazol-2-yl-idene]dichloridophenyl-gold(III) with silver bis-(trifluoro-methane-sulfon-yl)imide in the presence of traces of water. In contrast to corresponding Au(I) complexes, the core struc...

The title compound, [(UO(2))(2)Cl(2)(OH)(2)(H(2)O)(4)], was obtained unintentionally as the product of an attempted reaction between uranium(VI) oxide dihydrate, UO(3)·2H(2)O, and hydrogen bis-(trifluoro-methyl-sulfon-yl)imide (HTf(2)N), in an experiment to obtain crystals of uranyl bis-(trifluoro-methyl-sulfon-yl)imide, UO(2)(Tf(2)N)(2)·xH(2)O. The structure consists of neutral dimers of urany...

A series of 17 long-chain arylpiperazines containing bulky, complex imide systems (5,8-dimethyl-3b,9-epoxy-(3a,4,5,6,7,8,9,9a)-octahydro-1H-benzo[e]isoindole-1,3(2H)-dione or 4,9-diphenyl-4,9-epoxy-3a,4,9,9a-tetra-hydro-1H-benzo[f]isoindole-1,3(2H)-dione) was synthesized and evaluated for their affinity for serotonin 5-HT1A, 5-HT2A and dopamine D2 receptors. Most of the new compounds showed mod...

Glutarimidedioxime (H(2)A), a cyclic imide dioxime ligand that has implications in sequestering uranium from seawater, forms strong tridentate complexes with UO(2)(2+). The stability constants and the enthalpies of complexation for five U(VI) complexes were measured by potentiometry and microcalorimetry. The crystal structure of the 1 : 2 metal-ligand complex, UO(2)(HA)(2)·H(2)O, was determined...
