In this study, π‐conjugated poly(arylenevinylene)s are synthesized via the Pd‐catalyzed dehydrogenative direct alkenylation of polyfluoroarenes with diethenyl aromatic monomer. The introduction of a fluoro group promotes the cross‐coupling reaction, and the formation of the undesired homocoupling byproduct is minimized by optimizing the reaction conditions. The polycondensation reactions lead to the formation of poly(arylenevinylene)s with a well‐defined trans ‐configuration. The obtained polymers are evaluated as emitting materials for organic light‐emitting diodes.
