Synthesis and evaluation of fluorescent materials for colour control of peroxyoxalate chemiluminescence. II. Violet and blue emitters

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.
