The aim of this chapter is to give an overview of how and where ionic liquids have been and are used in optical spectroscopy. Optical properties of prominent ionic liquids themselves will be presented and then their application as solvents for UV-Vis and luminescence spectroscopy will be discussed. However, special care has to be taken to ensure that the ionic liquids used are optically pure. As the optical determination of ionic liquid acidity is one of the most important applications of optical spectroscopy in and of ionic liquids, a whole chapter has been dedicated to this topic. To limit the length of this overview neither mixtures of ionic liquids nor mixtures of ionic liquids with other solvents are discussed. Available literature published until fall of 2008 has been taken into account. [Pg.286]

Optical temperature sensor (opt(r)odes) based on the viscosity-dependent intramolecular excimer formation of l,3bi(l-pyrenyl)propane in [C4mypr][Tf2N] have been developed [33], The relative intensity of the excimer emission was found to gain in intensity with higher temperature. This has been attributed to the generally low viscosity of the ionic liquid. The working temperature of this luminescence thermometer is between 25°C and about 150°C. [Pg.292]

Time resolved studies on dye molecules can help to elucidate the solvation dynamics and can give information on the time constants of diffusion of the ionic components of an RTIL [69-75], Time resolved fluorescence studies show the diffusional motion of the dissolved solutes [76], Luminescence quenching of fluorescent transition metal dyes by oxygen has been used in case of so-called core-shell soft-sphere ionic liquids [77] to monitor the oxygen permeability of these ILs [78],... [Pg.297]

Many applications have been reported for ionic liquid crystals. Among these, most important applications related to their intrinsic or induced luminescent properties [22, 53, 64, 71-79, 112, 114-116]. To this purpose, metallomesogens containing... [Pg.111]
