| Abstract: | The emission spectra and photophysical behaviour of poly(1-naphthyl methacrylate) singlet state were investigated in solvents of different thermodynamic character. The quantum yields of monomeric emission, the life-times of the isolated unit and the rate constants for the quenching by biacetyl were evaluated. The same measurements were carried out for the monomeric (1-naphthyl acetate) and dimeric (di-1-naphthyl glutarate) model compounds. The data allow discussion of the effects of solvent on excimer formation and intramolecular energy migration. |
