摘要
PURPOSE: A poly(1,4-phpenylenevinylene)-based electroluminescent polymer and a polymer electroluminescent diode employing the polymer are provided, to improve the solubility and the properties of an electron transport layer of the polymer by introducing a 1,3,4-oxadiazole derivative or an alkoxyphenyloxy substituent. CONSTITUTION: The electroluminescent polymer contains the poly(1,4-phenylenevinylene)-based structure having a 1,3,4-oxadiazole derivative or an alkoxyphenyloxy substituent. The polymer has a molecular weight of about 10,000-600,000. Preferably the polymer contains a hetero atom selected from the group consisting of O, S, N, Si, Ge and carbon-carbon triple bond, in the poly(1,4-phenylenevinylene)-based structure.
