Infrared vibrational spectroscopy was used to probe concentration-dependent ion pair dissociation of imidazolium-based ionic liquids with three different halide anions (I- , Br- , and Cl- ) in deuterated chloroform. Dissociation of the ion pairs at l

Water-soluble, carbazole-based two-photon excitable fluorescent probes MPVC-I (“turn-on”) and MPVC-II (“turn-off”) are rationally designed and synthesized for the selective monitoring of carbon monoxide (CO). Both probes can effectively measu

Advantage of ionic liquids as designer solvents can be maximized by mixing different ionic liquids (ILs) for a possibility of continuous tunability of material properties. The property of these mixed ILs would be determined by their microscopic confo

Imidazolium-based ionic liquids having different anions 1-butyl-3-methylimidazolium ([BMIM]X: X = Cl(-), Br(-), I(-), and BF4(-)) and their aqueous mixtures were investigated by IR absorption and proton NMR spectroscopy. The IR spectra of these ionic

Ionic liquids of 1-butyl-3-methylimidazolium ([BMIM]) cation with different anions (Cl- , Br- , I- , and BF4- ), and their aqueous mixtures were investigated by using Raman spectroscopy and dispersion-included density functional theory (DFT). The cha

Unique fluorescence behavior was reported in room-temperature ionic liquids having imidazolium cations. Due to the molecular electronic energy level of the imidazolium cation, fluorescence in the visible range from pure ionic liquids is not expected,

Ionic liquid mixtures have gained attention as a way of tuning material properties continuously with composition changes. For some mixture systems, physicochemical properties such as excess molar volume have been found to be significantly different f

The observation of fluorescence in the visible spectral range in imidazolium-based ionic liquids, in which the peak of the fluorescence spectrum shifts with the change in the excitation wavelength by over 200 nm, was reported by Samanta and co-worker

The catalytic efficiency of diol-based organocatalysts has been shown to strongly depend on the diols molecular structure including hydrogen-bonding, yet, the underlying molecular-level origins have remained elusive. Herein a study on the inter- and
