The time-resolved emission spectra of a series of di-{beta}-substituted 1,n-dinaphthylalkanes have been investigated in isooctane at room temperature. Phosphorescence from the triplet excimer has been observed for the longer alkyl chain derivatives (n = 3,4) but not from the short-chain species (n = 1,2). Under identical experimental conditions, the excimer phosphorescence from the {beta}derivatives is blue shifted and is much weaker than that of the corresponding {alpha} isomers. Furthermore, the decay rates are much greater for the di-{beta} molecules. These results confirm the previously proposed L-shaped structure of the triplet excimers of naphthalene.
