TRICYCLIC ARYLAMINE POLYMERS-CONTAINING ELECTRONIC DEVICES

摘要

PROBLEM TO BE SOLVED: To provide an electroluminescence device having improved conductivity at low voltages as well as higher device efficiency.

SOLUTION: The electroluminescence device comprises a film disposed between an anode and a cathode so that the film emits visible light penetrating through a transparent outer part of the device under voltages applied. The film contains a polymer with a backbone having a repeat unit comprising a fluorene, a tricyclic arylamine, and a fluorene represented by the specified formula I.
