Abstract
Abstract The time-resolved fluorescence behaviour of dimethyl-2,6-naphthalenedicarboxylate (DMN) is investigated in three different solvents, i.e. cyclohexane, chloroform and 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). Measurements have been carried out at two different temperatures, i.e. 288 and 298 K. The influence of solvent polarity and refractive index as well as the effect of self-absorption on the fluorescence lifetime is discussed. With chloroform and HFIP additional measurements at higher DMN concentrations have been performed where excimer formation was observed. The excimer formation of DMN in these solvents can be explained by Birks kinetics model. The influence of the solvent on excimer formation and dissociation and its dependence on temperature and concentration is discussed.
