摘要：
A series of structurally related, poly(methacrylate)-based, cationic polysoaps of various geometries is studied by static and dynamic fluorescence measurements. The aggregation behavior in water is investigated by labeling the end groups of the polysoap backbones with a naphthyl fluorophore. The results strongly favor the model of "regional micelles", which evolve with increasing concentration from a mainly intramolecular association to an intermolecular one.
