Abstract

Steady-state and time-resolved fluorescence behavior of a 4-aminophthalimide-based surfactant probe has been studied in a mesostructured silica-surfactant nanocomposite. While the steady-state measurements indicate the location of the probe in the nanocomposite, the time-resolved study reveals the distinctive features of the solvation dynamics of the probe. Comparison of the present dynamical data with those reported for the parent fluorophore in other organized assemblies suggests the involvement of constrained water molecules near the ionic interface in the observed dynamics.
