Abstract

Donor - acceptor phenylene ethynylene systems containing the 6-methylpyran-2-one group, synthesized via classic or microwave-assisted Sonogashira cross-coupling, exhibit pronounced solvatochromism in fluorescence suggesting a highly polar excited state; 4-[4-(4-N,N-dihexylaminophenylethynyl) phenylethynyl]-6- methylpyran- 2- one has a fluorescence quantum yield > 0.9 in cyclohexane.
