Abstract
The fluorescence spectra of polyacenaphthylene and poly-1-vinylnaphthalene films and solutions have been studied between 77 and 450°K. Excimer fluorescence only is observed in films. The ratio of monomer to excimer fluorescence intensities is a function of temperature for solutions. The influence of temperature on the intensity of monomer and excimer fluorescence has been analysed according to a general kinetic treatment. Activation energies for excimer formation and dissociation have been measured.
