Abstract

This report discusses the transport properties of ionic liquid mixtures that incorporate a series of asymmetrical dications, including heterodications. The dicationic ILs combine either triphenylphosphonium and trimethylammonium cationic sites that are bridged to methylimidazolium or methylpyrrolidinium cationic sites. Mixtures were made of the dicationic bis(trifluoromethylsulfonyl)amide ionic liquids with N-ethoxyethyl-N-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide. The IL mixtures were characterized for their transport properties (temperature dependent conductivity and viscosity) and thermal properties (melting point and glass transition point).

Exploring the Use of Ionic Liquid Mixtures to Enhance the Performance of Dicationic Ionic Liquids

Journal Article Lall-Ramnarine, Sharon I. ; Suarez, Sophia N. ; Fernandez, Eddie D. ; ... - Journal of the Electrochemical Society

Dicationic ionic liquids (DILs) of diverse structural architectures (including symmetrical and asymmetrical ammonium, phosphonium and heterodications and the bis(trifluoromethylsulfonyl)amide (NTf₂^-) anion) have been prepared and used as additives to N-methyl-N-ethoxyethylpyrrolidinium (P₁EOE) NTf₂, a relatively high-performing IL in terms of its transport properties (viscosity 53 mPa s). The three-ion, binary IL mixtures were characterized for their thermal and transport properties using differential scanning calorimetry, temperature dependent viscosity, conductivity and Pulsed Gradient Spin Echo (PGSE) NMR. Variable temperature ¹H, ¹⁹F and ³¹P self-diffusion coefficients were determined at 25, 60 and 75°C. The order of the diffusion coefficients was D(P₁EOE⁺) > D(anion) >more »« less

Effects of Aromaticity in Cations and Their Functional Groups on the Low-Frequency Spectra and Physical Properties of Ionic Liquids

Journal Article Kakinuma, Shohei ; Ramati, Sharon ; Wishart, James F. ; ... - Journal of Physical Chemistry. B, Condensed Matter, Materials, Surfaces, Interfaces and Biophysical Chemistry

We investigate the temperature dependence of low-frequency spectra in the frequency range of 0.3–200 cm^-1 for ionic liquids (ILs) whose cations possess two systematically different cyclic groups, using femtosecond Raman-induced Kerr effect spectroscopy. The target ILs are bis(trifluoromethylsulfonyl)amide [NTf₂]– salts of 1-cyclohexylmethyl-1-methylpyrrolidinium [CHxmMPyrr]⁺, 1-cyclohexylmethyl-3-methylimidazolium [CHxmMIm]⁺, N-cyclohexylmethylpyridinium [CHxmPy]+, 1-benzyl-1-methylpyrrolidinium [BzMPyrr]⁺, 1-benzyl-3-methylimidazolium [BzMIm]⁺, and N-benzylpyridinium [BzPy]⁺ cations. The aim of this study is to better understand the effects of aromaticity in the cations’ constituent groups on the temperature-dependent low-frequency spectral features of the ILs. The low-frequency spectra of these ILs are temperature dependent, but the temperature-dependent spectrum of [CHxmMPyrr][NTf₂] is different frommore »« less

Supercapacitive properties of micropore- and mesopore-rich activated carbon in ionic liquid electrolytes with various constituent ions

Journal Article Nguyen, Quoc Dat ; Patra, Jagabandhu ; Hsieh, Chien-Te ; ... - ChemSusChem

Ionic-liquid (IL) electrolytes, characterized by large potential windows, intrinsic ionic conductivity, low environmental hazard, and high safety, are used for micropore- and mesopore-rich activated-carbon (AC_micro and AC_meso) supercapacitors. IL electrolytes consisting of various cations [1-ethyl-3-methylimidazolium (EMI⁺), N-propyl-N-methylpyrrolidinium (PMP⁺), and N-butyl-N-methylpyrrolidinium (BMP⁺)] and various anions [bis(trifluoromethylsulfonyl)imide (TFSI^-), BF₄^-, and bis(fluorosulfonyl)imide (FSI-)] are investigated. The electrolyte conductivity, viscosity, and ion transport properties at the AC_micro and _ACmeso electrodes are studied. In addition, the capacitance, rate capability, and cycling stability of the two types of AC electrodes are systematically examined and post-mortem material analyses are conducted.

Ionic Liquid–Solute Interactions Studied by 2D NOE NMR Spectroscopy

Journal Article Khatun, Sufia ; Castner, Edward W. - Journal of Physical Chemistry. B, Condensed Matter, Materials, Surfaces, Interfaces and Biophysical Chemistry

Intermolecular interactions between a Ru²⁺(bpy)₃ solute and the anions and cations of four different ionic liquids (ILs) are investigated by 2D NMR nuclear Overhauser effect (NOE) techniques, including {¹H-¹⁹F} HOESY and {¹H-¹H} ROESY. Four ILs are studied, each having the same bis(trifluoromethylsulfonyl)amide anion in common. Two of the ILs have aliphatic 1-alkyl-1-methylpyrrolidinium cations, while the other two ILs have aromatic 1-alkyl-3-methylimidazolium cations. ILs with both shorter (butyl) and longer (octyl or decyl) cationic alkyl substituents are studied. NOE NMR results suggest that the local environment of IL anions and cations near the Ru²⁺(bpy)₃ solute is rather different from the bulkmore »« less

Interactions between water and 1-butyl-1-methylpyrrolidinium ionic liquids

Journal Article Fadeeva, Tatiana A. ; DeVine, Jessalyn A. ; Castner, Edward W., E-mail: ed.castner@rutgers.edu ; ... - Journal of Chemical Physics

We report experimental results on the diffusivity of water in two ionic liquids obtained using the pulsed-gradient spin-echo NMR method. Both ionic liquids have the same cation, 1-butyl-1-methylpyrrolidinium, but different trifluoromethyl-containing anions. One has a strongly hydrophobic anion, bis(trifluoromethylsulfonyl)amide, while the second has a hydrophilic anion, trifluoromethylsulfonate. Transport of water in these ionic liquids is much faster than would be predicted from hydrodynamic laws, indicating that the neutral water molecules experience a very different friction than the anions and cations at the molecular level. Temperature-dependent viscosities, conductivities, and densities are reported as a function of water concentration to further analyzemore »« less
