Large changes in optical response through chemical pre‐ordering of poly(p‐phenylenevinylene)

Abstract
Conjugated polymers such as poly(p‐phenylenevinylene), (PPV, see Figure), show real promise in optoelectronic applications. A new synthetic route to improved PPV is presented, involving the thermal conversion of a precursor polymer containing rigid rod conjugated segments joined by flexible spacer groups. A high degree of interchain ordering results which influences the optical response of the material. magnified image
