Abstract

We have previously reported into the extent of structuring in ILs using photochromic molecular probes1. In order for Ionic Liquids (ILs) to be fully utilized to their potential, it is necessary to have a complete understanding of their physical properties. In this study we investigated the thermophysical interactions in several pure and water-saturated ionic liquids being hydrophilic and hydrophobic in nature, namely 1-alkyl-3-methyl imidazolium and trihexyltetradecylphosphonium family of ILs. The density, viscosity and conductivity of pure and water-saturated imidazolium and phosphonium-based ILs were measured over a broad temperature. Moreover, interactive and binding energies of the studied imidazolium ILs in the presence of H2O molecules were calculated using Gaussian and compared with experimental Raman spectroscopy of the same imidazolium ILs, with and without the presence of saturated water.
