Abstract

Results are presented which include the synthesis

characteriation and electroluminescence performance of a new type of conjugated polymer

poly(2

5 diphenyl 1

4 oxadiazolyl) 3

3' vinylene(M PPV). In order to synthesize compound (A)

two reaction routines were chosen

but experimental result showed that routine(1) was much more promising than that of routine(2). A light emitting diode with the structure of ITO/M PPV(80nm)/A1(150nm) is driven at about 6V and has a peak emission wavelength of 470nm

while the LED constructd using PPV(ITO/PPVA1) emitted yellow light.The most likely explanation on the differece is that a decrease in the conjugation length of the heterocycle-substituted PPV(M-PPV）increases the band gap to values higher than that of PPV

resulting in a blue shift in the emission apectrum and this is in agreement with the result determined by XPS technique.
