The fluorescence emission of pyrene end-labelled polyethyleneoxide samples (/Vl, = 0.16.104 1.95.104) has been studied in dilute solution at 20 Β°. Intramolecular "excimer" fluorescence of increasing intensity is observed with decreasing molecular weight. The influence of the molecular weight on the
