Original Abstract

In this paper we investigate the fluorescence measurement of the molecular probe Prodan in cationic micellar solution of cetyltrimethylammonium bromide (CTAB). Photophysical behaviour of Prodan is strongly dependent on polarity of its environment. The excited molecules of Prodan can exist in two different forms – the locally-excited state (LE), from which molecules of Prodan can switch to lower-energy intramolecular charged transfer state (ICT) due to strong interaction with molecules of solvent. In nonpolar environments Prodan emits from LE state, while in polar environments the emission is from ICT state. Time-resolved fluorescence spectra (TRES) and deconvolution of steady-state emission enable an interpretation of three different locations of Prodan molecules in micellar aggregates.
