SYNTHESIS OF POLY(2,5-DIPHENYL-1,3,4-THIADIAZOLYL)-4,4'-VINYLENE AND ITS ELECTROLUMINESCENT PERFORMANCE*

Received Date: 6 April 1998

The synthesis, characterization and electroluminescence performance of a new type of conjugatedpolymer, poly(2,5-diphenyl-1,3,4-thiadiazolyl)-4,4'-vinylene (TPPV) are presented. A light-emitting diodeconsisted of ITO/TPPV/Al is driven at about 4.0 V and has a peak emission wavelength of 485 nm. Thisblue-shift of the peak is due to the decrease of conjugate degree of TPPV compared to PPV. This result is inaccord with that determined by XPS and theoretical model of MNDO/3
