Abstract

The emission properties and absorption spectra of 1,3-di(a-naphthyl)propane and 1,3-di(b-naphthyl)propane in ethylene glycol-water mixtures were investigated. In the temperature region of -196 to 60? they exhibit new absorption and fluorescence spectra, which are attributable to the dimer formed between the 2 intramol. naphthyl groups. Above 60? the dimers decompose, only monomer and excimer fluorescenece can be observed
