Popis:	The behaviour in aqueous medium of cationic amphiphilic copolymers derived from 3-vinylpyridine has been studied. The ability of these polymers to form hydrophobic microdomains was shown by fluorescence spectroscopy using a molecular rotor as a fluorescent probe, and the resulting structure was visualized by cryo-transmission electron microscopy (cryo-TEM). The parameters (shape and size) obtained from cryo-TEM are discussed in relation to the copolymer composition and the local viscosity defined by the rotor fluorescence quantum yield.
