9,10-Bis(phenylethynyl)anthracene (BPEA) derivatives were synthesized from 10-bromo-9-anthracenecarbaldehyde by stepwise Sonogashira coupling with phenylethynes and the one-shot double-elimination reaction with benzyl phenyl sulfones. Those two reactions could be integrated in a one-pot process to give unsymmetrically substituted BPEA derivatives in good yields by simple operations. This integrated process was applied to the synthesis of an extended BPEA derivative having an extra phenylethynyl group. The photophysical properties of the BPEA derivatives were investigated by UV/Vis and fluorescence spectroscopy. Georg Thieme Verlag Stuttgart · New York.

Four novel diarylanthracene derivatives (1, 5a, 5b, 6) have been synthesized by Suzuki and Sonogashira coupling reactions, characterized and their structure assigned by 1H and 13C NMR spectroscopy. The spectral and photophysical properties of a series of symmetrically and asymmetrically disubstituted anthracene-based compounds (1-6) and of benzothiadiazole derivative 7 have been studied. All these photostable systems show high fluorescence emission and a batochromic shift of the absorption spectrum that increase with π-conjugation. Flash photolysis measurements were carried out on the poor fluorescent compound 4.
