Femtosecond solvation dynamics study of hydrophobic and hydrophilic probes in various room temperature ionic liquids (RTILs) containing microemulsions

The locations of hydrophobic and hydrophilic probes in room temperature ionic liquids (RTILs) containing microemulsions have been investigated using femtosecond solvation dynamics study, as the time correlated single photon counting (TCSPC) measurement has limitation in terms of detecting the ultrafast component of relaxation time less than 100 ps. Here, choice of two different RTILs unveils the information about the effect of acyclic and cyclic hydrocarbon chain on solvation dynamics. The exclusive information from dynamic light scattering (DLS) measurement, anisotropy study and the fluorescence correlation spectroscopy (FCS) judiciously help to perform detailed analysis of these systems.
