Room temperature ionic liquids (ILs) are currently being studied as new solvent media for a variety of purposes. Our interest lies in understanding solvation energetics and solvation dynamics in this distinctive environment. Steady-state and time-resolved fluorescence spectroscopy are used to measure solvation energies and dynamics in several series of imidazolium, pyrrolidinium and ammonium ionic liquids. The combination of femtosecond Kerr-gated emission spectroscopy and picosecond time correlated single photon counting are used to measure the full solvation response in ionic liquids. The observed solvation dynamics is highly non-exponential and extends over four decades in time. This non-exponential temporal response probably originates from dynamical heterogeneity similar to that found in supercooled liquids.
