Optical spectroscopy and ionic liquids.
Ionic liquids have shown to be excellent solvents for optical investigation of solutes. Transition metal complexes as well as f-element compounds have been studied in ionic liquids. Not only are neat and clean ionic liquids transparent in the NIR and visible region, but the absence of anions with low frequency oscillators such as C-H, N-H and O-H have been found to be favourable when it comes to photoluminescence and future applications can be envisioned. Of fundamental interest is the study of the absorption spectra of organic dyes dissolved in an ionic liquid as the many physicochemical parameters such as the dipolarity and polarizability of the ionic liquid and its hydrogen bond ability can be determined.
