Properties of ionic liquids containing silver(I) or protic alkylethylenediamine cations with a bis(trifluoromethanesulfonyl)amide anion

Protic Ionic Liquids: Evolving Structure–Property Relationships and Expanding Applications

“…Because of the hydrophobic anion and large amount of hydrocarbon present in the cation, the highest water solubility in the PILs was 0.1 wt % for the alkyl group being 2-ethylhexyl, whereas the lowest was for the alkyl groups being decyl or dodecyl with water solubility <0.1 wt %. 161 Hexane and cyclohexane had solubilities <0.1% for all of the PILs, whereas benzene increased in solubility with increasing alkyl chain length on the cation varying in solubility from <0.1 to greater than 10 wt % for this series of PILs. Chloroform and diethyl ether were more than 10 wt % soluble in all of them except for the PIL with the butyl group on the cation.…”

“…160 The physicochemical properties of 6 PILs and 3 silvercontaining AILs were investigated, and the differences between proton and silver-containing ILs were compared. 161 The AILs consisted of a double-chained alkylethylenediamine silver(I) cation paired with the Tf 2 N anion, and the PILs of singlechained alkylethylenediammonium salts also paired with the Tf 2 N anion. The alkyl group on the PILs varied with increasing alkyl chain length between butyl to dodecyl, along with the branched 2-ethylhexyl.…”

“…121 For example, in materials synthesis the use of silver-containing ILs to form colloidal silver(0) could only be achieved from the strongly nanostructured Ag-(octylethylenediaminium) 2 TFSA, and poorer quality or no nanoparticles from the analogous ILs with shorter alkyl chains. 161 A hierarchically structured silica has been synthesized using the nonionic block copolymer P123 and EAN leading to micropores and mespores with average sizes of 1.0 and 4.5 nm, respectively. 174 The micropores were templated from the nanostructure of the EAN, and the mesopores from a P123−EAN lyotropic liquid crystal phase.…”

Liquid Nickel Salts: Synthesis, Crystal Structure Determination, and Electrochemical Synthesis of Nickel Nanoparticles

“…[8][9][10][11][12][13] Several examples of electrodepositiono fm etals from liquid metal salts can be found in the literature. [14][15][16][17][18][19][20][21][22] Our research group has obtainedv ery promising resultsf or the electrodeposition of copper, [23][24][25] silver, [26][27][28][29][30] palladium [31] and lithium. [32] Metal coatings of ag ood quality were achieved at very high current densities,e ven withoutt he use of additives.…”

Thermal properties and crystal structures of cobalt(III)–cyclam complexes with the bis(trifluoromethanesulfonyl)amide anion (cyclam = 1,4,8,11-tetraazacyclotetradecane)

“…Ionic liquids are salts with melting points below 100°C, and they have recently attracted much attention for both pure and applied science [10][11][12][13][14][15][16]. Several ionic liquids from metal-chelate complexes have been reported recently [17][18][19][20][21]. We prepared ionic liquids comprising cationic metal-chelate complexes and the bis(trifluoromethanesulfonyl)amide anion ([Tf 2 N] À ), which exhibit vapochromism, thermochromism, and the spin-crossover phenomenon [22,23].…”
