A series of bis(phenylethynyl)benzenes 3 and 9,10-bis(phenylethynyl)anthracenes 4 was synthesized by bromination-dehydrobromination reaction or newly developed direct triple bond formation reaction from styrylstilbenes 1 or distyrylanthracenes 2.Subsequently systematic investigations were carried out on their absorption and fluorescence spectra, and their chemiluminescence properties.The following points are apparent; (a) a linear relationship between and Hammett's ?P of compounds 3 and 4 was observed, (b) a significant relationship between Stokes' shift of 4 and ?P was observed and (c) in the series of compounds 4 the electron-donating ability of the substituents has a pronounced effect on the chemiluminescence properties.

A number of bis(phenylethynyl)-substituted anthracenes and naphthacenes have been synthesized and their suitability as fluorescent additives for peroxyoxalate chemiluminescence evaluated.Fluorescence and chemiluminescence emission data for all compounds are presented.Both 2-chloro- and 6-chloro-5,12-bis(phenylethynyl)naphthacene provide effective scarlet chemiluminescence with the peroxyoxalate system (λmax 609 and 614 nm respectively).Althgough solutions of both compounds decolorize slowly in the presence of air and light, when used in concentrations 0f 1-5*10-3 M they allow efficient chemiluminescence for greater than 5 h.
