Abstract
The invention relates to poly(phenylene vinylene) polymers substituted with dendritic sidechains to enhance main-chain separation in the solid state. The polymers are synthesized by the Heck polymerization and have a weight-average molecular weight of 20,000 to 60,000 Daltons. The polymers are self-ordering in the solid state and have thermotropic liquid crystalline phases. The polymers show enhanced photoconductivity, better charge transport capability and improved polarized light emission.
