| Abstract
| - The effects of confinement of the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate on solvationdynamics and rotational relaxation of Coumarin 153 (C-153) in Triton X-100/cyclohexane microemulsionshave been explored using steady-state and picosecond time-resolved emission spectroscopy. The steady-stateand rotational relaxation data indicate that C-153 molecules are incorporated in the core of the microemulsions.The average rotational relaxation time increases with increase in w ([bmim][BF4]/[TX-100]) values. The solventrelaxation in the core of the microemulsion occurs on two different time scales and is almost insensitive tothe increase in w values. The solvent relaxation is retarded in the pool of the microemulsions compared to theneat solvent. Though, the retardation is very small compared to several-fold retardation of the solvation timeof the conventional solvent inside the pool of the microemulsions.
