Abstract
Synthetic approaches to efficient blue fluorescent compounds suitable for use in peroxyoxalate chemiluminescence systems are described. Various bis(phenylethynyl)-naphthalenes and -phenan-threnes were obtained but these were shown to produce purple fluorescence and chemiluminescence. Ring substitution of 9,10-diphenylanthracene, however, afforded a number of satisfactory blue fluorescent emitters. The structure and derivation of several byproducts is also discussed.
