Abstract

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.
