Dynamic solvation of the dye, coumarin 153, is compared in an ionic liquid that forms micelles in wateragainst the bulk solvent. This provides the unprecedented opportunity of investigating the behavior of theionic liquid in two globally different configurations. It is proposed that the imidazolium moiety is in bothcases responsible for the majority of the solvation, which manifests itself in the first 100 ps. Exploiting theuse of ionic liquids capable of accommodating specific structures thus provides a deeper insight into howsolutes interact with these fascinating and interesting solvents (at least those that are imidazolium based) thatare gaining ever increasing interest in the scientific community.
