Synthesis and Absorption/Emission Spectroscopic Properties of Bis(phenylethynyl)benzenes and 9,10-Bis(phenylethynyl)anthracenes

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.

Direct CC Triple Bond Formation from the C=C Double Bond with Potassium tert-Butoxide in Dimethylformamide containing Trace Amounts of Oxygen

A novel and facile method for direct acetylenic bond formation from the C=C double bond by treatment with KOBut in dimethylformamide has been found both in a 9,10-bis(4'-substituted styryl)anthracene series and in a 4-substituted 4'-nitro-stilb

SYNTHESIS OF 9,10-DIACETYLENYLANTHRACENES

Syntheses are reported for 9,10-bis(phenylethynyl)anthracene and its derivatives containing identical and different substituents in the phenyl groups by the acetylenic condensation of 9,10-dibromoanthracene.The introduction of a donor substituent into one phenyl group and a withdrawing substituent into the other leads to a significant shift of the fluorescence maximum toward longer wavelengths.
