The micellar behavior of poly [ N ‐ p ‐vinylbenzyl‐ O ‐β‐ D ‐galactopyranosyl‐(1→4)‐ D ‐gluconamide] (PVLA) were studied by fluorescent spectroscopy, dynamic light scattering (DLS), and fluorescence energy transfer experiments using fluorescent probes such as pyrene, carbazole, and anthracene. It was found that the amphiphilic PVLA formed polymer micelles in water due to the presence of the hydrophobic polystyrene backbone and hydrophilic sugar moieties. The particle size of PVLA micelles in aqueous solution were about 8.3 nm in number average. The critical micelle concentration (CMC) of PVLA was found to be about 1×10 –4 M when pyrene was used as a probe. The same results were observed from the fluorescence energy transfer experiments using carbazole and anthracene.
