Acidic 1-ethyl-3-methylimidazolium fluoride: a new room temperature ionic liquid

Catalytic Activities of Pt–Metal Alloys on Oxygen Reduction Reaction in Fluorohydrogenate Ionic Liquid

“…[1][2][3] Our group has focused on fluorohydrogenate ILs (FHILs), which consist of organic cations and fluorohydrogenate anions, (FH) n F ¹ , where n represents the average number of HF ligands attached to the fluoride anion. One of the firstly developed FHILs, 1-ethyl-3-methylimidazolium fluorohydrogenate (EMIm-(FH) 2.3 F), exhibits high conductivity (100 mS cm ¹1 at 298 K), low melting point (208 K) and low glass-transition temperature (148 K), 4,5 making it a promising electrolyte for electrochemical devices.…”

Influence of Dopant Type and Orientation of Silicon Anodes on Performance, Efficiency and Corrosion of Silicon–Air Cells with EMIm(HF)2.3F Electrolyte

“…One of the possible approaches is the usage of EMIm(HF) 2.3 F electrolyte which possesses high conductivity, low viscosity and chemical stability in air. [7][8][9][10] The proof of concept, that substantial discharge was possible when using EMIm(HF) 2.3 F electrolyte, was proposed in 2010 according to the following reactions: 11 Anode: Si + 12(HF) 2 Additionally, a screening of several anode materials -As-, Sband B-doped Si wafers -was performed, in which the cell potential at intermediate current densities as determined from potentiodynamic polarization measurements, was set as major criterion. The corrosion current densities as obtained by the Tafel fits from the polarization experiments for the different wafer types were also considered for the material selection.…”

Iron Fluoroanions and Their Clusters by Electrospray Ionization of a Fluorinating Ionic Liquid

“…-was generated according the method of Hagiwara by condensing anhydrous HF onto 1-ethyl-3-methylimidazolium chloride [13] -in the 9:1 acetonitrile:water solvent. In one experiment, an aliquot of the aqueous iron(III) chloride solution was treated with approximately 1000 molar equivalents of hydrogen peroxide relative to Fe to ensure all of the iron in solution was iron(III) prior to mixing with pure acetonitrile.…”

“…This was surprising since the fluorohydrogenate anion forms a more stable complex than the chloride anion in the condensed phase [13]. This experiment was conducted using -(triflimide).…”

“…For example, fluoroanions can be used to probe new bonding motifs in organometallic complexes, involving metals that include B [1], Co [2][3][4][5][6], Ga [7], As [1], Cd [8], Pd [9], In [7], Sn [10], and U [11]. One of the most intriguing properties of fluoroanion-containing materials is the ability to solvate HF, which has the potential to provide improved safety and efficiency for synthetic chemistry [7,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. For example, anhydrous HF-containing systems have great utility for synthesis of high oxidation state fluoroanions, such as [AgF 4 ]…”
