Description
Summary:Synthesis of the pairs of positional isomers of the title compounds is based on utilization of two isomeric o , o -dibromo dialdehydes and a selective ortho -metallation/Friedel-Crafts cyclization sequence of the corresponding diacetals. Photophysical and electrochemical properties of the new group of fluorescent and photoresistant compounds have also been performed. A series of photoresistant, positional isomers of o -bromo(hetero)acenaldehydes containing RO-Ar and bifunctional ortho -CHO/Br structural motifs, is available in the peculiar Friedel-Crafts modification, using isomeric aromatic o , o -dibromodialdehydes.
