摘要
利用双卤甲基苯衍生物在强碱（ＫＯＢｕ）诱导下的缩合反应，合成了共轭态可溶的聚（２，５—二庚基）对苯乙炔，并利用ＩＲ、ＵＶ—Ｖｉｓ、１Ｈ－ＮＭＲ、ＴＧＡ等对聚合物结构与性能进行了表征。其Ｍｎ＝０．４８×１０４。电致发光器件的发光峰值波长为４８６ｎｍ（蓝光），起亮电压为２２Ｖ。
Poly(2,5-diheptyl-1,4-phenylenevinylene), a blue-light emitting polymer, was prepared through dehydrohalogenation polymerization of bis(chlomethyl)benzene and its dervatives. The resulting polymers were characterized by IR, UV-Vis, 1 H-NMR, GPC and TGA. Its molecular weight were , M n=0.48×10 4 , M w=3.65×10 5 , respectively .Polydiepersity index was 7.6. Emission peak wavelength of EL cell based on PDHPV was 486nm(blue light),turnon voltage was 22 V.
