The polyphosphazene (PPZ) of polymers with a regular oligopolyphenylene vinylene (PPV) as a side chain was synthesized by the nucleophilic substitutive reaction of a reactive polydichlorophosphazene of inorganic polymers and a functional oligopolyphenylene vinylene. The obtained graft copolymers of the polyphosphazene-oligopolyphenylene vinylene (PPZ-g-PPV) were characterized in structures and measured in properties with NMR ( 31 P, 1H, 12 C) ,FT-IR, GPC, DSC and TGA etc. The luminous devices of the polymer were manufactured with the synthesized polymers as luminous materials . And the device property was studied preliminarily. The experiment results showed that the polymer possess the property of excellent solubility and film-forming . Through the spin-coating method the luminescent film can be gained and satisfy to the requirements. The luminous wave length of PELD is 412nm and is a blue electrogenerated light. Temperatures of the glass transition and initial thermal decomposition of the polymer are 97?℃ and 387?℃ respectively.
