Fluorescence behavior of octadecylrhodamine B (ORB) and the association-dependent changes in UV-VIS absorption and fluorescence spectra in aqueous solutions were studied by UV-VIS absorption spectroscopy and steady-state and time-resolved fluorometry. Spectral changes are interpreted in terms of the hydrophobically driven formation of H- and J-dimers and higher aggregates. The knowledge gained serves as a basis for the interpretation of results of the fluorescence correlation spectroscopy study of polymeric micelles labeled with ORB.
