✦ Synopsis
Emission spectra and photobehaviour were investigated for polymers and copolymers derived from poly(methyl methacrylate) with one to three phenyl groups for each monomer molecule. The results show that excimer emission increases with the number of phenyl groups for the structural unit and with the temperature, and that it decreases when the thermodynamic character of the solvent improves. The results are interpreted in terms of excimer formation between non-nearest neighbours.
