Conjugated copolymers were obtained by the polymerization of 2
5-bis(4-bromo-benzene)-1
3
4-oxadiazole (M-Ⅰ) and 1
4-divinyl-2
5-dibutoxybenzene (M- Ⅱ) through Pd-catalyzed Heck reaction.Bothmonomers and polymer were characterized by NMR
MS
FT-IR
UV

GPC
elemental analysis and thermal analysis. The 1
3
4-oxadiazole unit is a chromophore
having good hole-transporting property and oxygen and heat stability. The polymer can emit very strong green fluorescence.It is expected to be used as polymer materials with electro-optical properties.
