Three types of poly(4-diphenylaminostyrene) (PDAS) having different polymer chain structures were prepared by living anionic polymerization, and the electroluminescence of PDAS/tris(8-hydroxyquinoline) aluminum (Alq3) blend films was examined. The hole drift mobility of PDAS increased with an increase in the syndiotactic configuration. The current density, turn-on voltage and brightness were also improved with an increase in the syndiotactic configuration of PDAS.
