The ¯uorescence of pyrenyl labelled polystyrene has been investigated. The ratio of excimer to monomer intensities (I e /I m ) is found to vary tortuously with increasing concentration (C) and displays two critical concentration points, C at about 3.2 Â 10 À2 g ml À1 and C m at about 0.32 g ml À1 .
The fluorescence behaviour of a series of acenaphthylene/methyl methacrylate copolymers covering a wide range of intramolecular chromophore compositions has been examined using pulsed laser excitation. The decay of emission intensity in the region of monomer fluorescence could be described only by t
