Abstract

New dipolar and non-dipolar poly (phenylenevinylene) dendrimers bearing electron- donating and electron-withdrawing groups have been efficiently synthesized using Heck and Horner-Wadsworth-Emmons reactions. The photoluminescence of these systems may be tuned in the blue zone by choosing the appropriate peripheral groups. Despite the meta- substitution pattern, large Stokes shifts can be observed when π-donor and π-acceptor ...
