摘要

联苯二胺

3′-二甲基联苯二胺在次氯酸钠介质中氧化制备了相应的N

N′-二氯联苯醌二亚胺

3′-二甲基 N

N′-二氯联苯醌二亚胺 .通过红外 (FT-IR)

核磁共振 (1H-NMR)等进行了表征 .研究了此化合物在二价镍配合物存在下

与 2

5-二溴噻吩制成的Grignard试剂共聚的方法

并得到了联苯醌二亚胺与噻吩交替共聚的共轭聚合物 .该合成方法所得聚合物的纯收率分别为 63%

88% .循环伏安测定表明该类聚合物具有一定的电化学活性

紫外-可见光谱中分别在 310nm

450nm处 (共聚物Ⅰ )和290nm

430nm处 (共聚物Ⅱ)出现吸收峰 .根据聚合物的粉末X-射线衍射图(XRD)

对所得聚合物的结晶性也做了初步探讨.

Abstract

New alternative π-conjugated copolymers were obtained by nickel(Ⅱ) complex catalyzed polycodensation of N

N'-diehlorediphenoquinonediimine or 3

3'-dimethyl-N

N'-dichloredipheno-quinone diimine with 2

5-thiophenylene dimagnesium dibromide．The monomers were prepared from the corresponding benzidines oxidized by NaOCl．The monomers were characterized by FT-IR and 1H-NMR．The eopolymers wele characterized by FT-IR

UV-Vis

cyclic vohammogram and XRD．The obtained eopolymers were partially soluble in DMF

DMSO and CF3COOH．The soluble part (in DMSO) of copolymer Ⅱ showed two absorption peaks at about 310 nm and 450 nm

respectively

while copolymer I showed two absorption peaks at about 290 nm and 430 nm

respectively．The results from cyclic vohammogram and XRD showed that the eopolymers had electrochemical activity

and the copolymers were amorphous．
