Solvent–solute interactions in ionic liquids

Excess molar volumes and viscosity behaviour of binary mixtures of aniline/or N,N-dimethylaniline with imidazolium ionic liquids having triflate or bistriflamide anion

“…This is in agreement with the hydrogen bond acidities of ionic liquids (α) listed in Table 5, in which their cations play the principle role [18,90]. Further on, both studied ionic liquids are also proton acceptors through their anions (the respective hydrogen bond basicities β given in Table 5 are mainly anion controlled [18,90] [82,91,92].…”

“…On the other hand, ionic liquids reveal very interesting fundamental features: i) they have specific structure represented by polar (ionic) and non-polar (aliphatic) domains [4], which is crucial for the aforementioned diverse solvent power and ii) they allow a variety of interactions in their mixtures: dispersion forces between aliphatic chains present in the mixtures of imidazolium ionic liquids with alcohols [15]; strong interactions such as ionic (Coulomb forces [16] and ion-dipole interactions [17]), hydrogen bonds [15,[18][19][20], and specific interactions with the aromatic compounds [21][22][23].…”

Characterization of Bamboo after Ionic Liquid-H2O Pretreatment for the Pyrolysis Process

“…In the ILs-H2O mixture, it has been suggested that water molecules were bound to two anions by forming hydrogen bonds (López-Pastor et al 2006). The strength of the hydrogen bonding between the anion and water molecules follows from the hydrogen bond accepting ability of the corresponding ILs (Crowhurst et al 2003). Therefore, the solubility of cellulose in ILs was decreased by adding H2O solvent.…”

Investigation of contrasting hydrogen bonding pattern of 3-(phenylamino)-cyclohexen-1-one with solvents in the ground and excited states

“…There are reports in the literature describing effects of multiple hydrogen bonding in different macromolecular system and in ionic liquids [47][48][49][50]. Studies on use of linear free energy relationship based analysis to investigate multiple solvation interactions of some ionic liquids with different probe molecules have been reported in literature [51,52]. Our present study uses Kamlet-Taft analysis to decipher the ground and excited state behavior of multiple hydrogen bonding sites in PACO.…”
