Solvation dynamics of coumarin 153 embedded in AOTÂ +Â phenol organogels studied by time-resolved fluorescence spectroscopy

► Organogels are composed by self-assembly with hydrogen bonds and dispersion forces. ► An emitting probe, coumarin 153 is embedded inside the organogel structure. ► ps-ns Fluorescence spectroscopy applied to measure dynamic fluctuations of gel. ► Spectral relaxations show dual aspects based on different modes of gel fluctuations.
