Notes:
Polystyrene/poly(ethylene oxide) diblock copolymers bearing anthracene or phenanthrene groups at the block junctions were synthesized by sequential anionic polymerization using cumylpotassium as initiator. Labelled copolymers were characterized by means of ultraviolet (UV) spectroscopy, gel-permeation chromatography (GPC) and 1H NMR spectroscopy. The solutions of the prepared copolymers in water and 1,2-dichloroethane/methanol mixtures were studied by fluorescence spectroscopy. The intermolecular energy transfer process confirms the presence of organized structures (micelles) in solutions.
