| Abstract: | 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.Both monomers and polymer were characterized by NMR,MS,FT-IR,UV,fluorescent spectroscopy,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. |
