| Abstract: | Copolymers containing alternating flexible aliphatic blocks and rigid poly(\%p\%\|phenylenevinylene) (PPV) blocks were synthesized and characterized. It was found that the fluorescent intensity increases with increasing length of the flexible blocks. Bright blue\|light emitting diodes were fabricated using PPV copolymers as electroluminescent layers. The devices show 190 cd/m\+2 light\|emitting brightness at 460 nm and 15 V turn\|on voltage. The effects of oxadiazole derivative PBD and tris(8\|hydroxyquinoline) aluminum Alq\-3 electron\|transporting layers on the luminance and stability of the devices are discussed.$$$$ |
