【 摘 要 】

The PPV related copolymers, TPA-PPV, TPA-POPV, TPA-ROPPV, and TPA-PBPV were synthesized by the Wittig polycondensation reaction to tune the emission wavelength from green to blue region. They showed UV-Vis. absorbance and PL in the ranges of 378 nm~440 nm and 447 nm~503 nm, respectively. The band gap energy of these copolymers were in the ranges of 2.53 eV~2.81 eV.
