SYNTHESIS OF 9,10-DIACETYLENYLANTHRACENES

Article abstract of DOI:10.1007/BF00962407

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.
