Abstract :
Bridged 1,6-diphenyl-1,3,5-hexatrienes were prepared from 1-indanone by successive Robinson annulation and McMurry coupling reaction. Rigidification produces a decrease in oxidation potential and HOMO-LUMO gap, and a considerable enhancement of fluorescence quantum yield compared to the open-chain analog.
