New Synthesis of Electrically Conducting PiーConjugated Heterocyclic Polymers

作为一种新的电调节异环聚合物的合成方法，使用pi-聚合物链上的聚合物系统，我们开发了用零-valent nickel复合体的二卤代多条件的方法。（n X-Ar-X + n Ni（0）Lm-> （Ar）_n + n NiX_2 Lm; Ar ：异质单元）.For example， reactions of zero-valent nickel complexes （ e.）g.，混合物（1， 5-环氯丁二烯）镍（0）、Ni（cod）_2和2， 2'-双吡啶）与3-烷基-2-，5-二硫醚制成多聚编码（3-烷基-2，5-噻吩） （PRTh）与分子重量约15000 - 150000。PRTH是在氯福中解决的，并在氯福解决方案中解决随机线圈的组成。PRTh的电影被放置在一个平台板的电极中，从氯论坛解决方案。PRTH在含有电解质的溶液中的电化学氧化（离子掺杂）是由胶片从黄色到蓝色的颜色变化引起的，而颜色变化是可逆的。这个观察指标，即PRTh可以在电子设备中使用。Pi-聚合共聚物，是固定的电子-接受2，5-硫烯环和电子-捐赠2.5-吡啶环，是由使用零-Valent Nickel复合体准备的。拥有它独特的电子结构，而共聚物显示稳定的电化学氧化状态。Besides是一种以上的聚合物，我们研究了其他电操作的pi--聚合物、聚合物的还原行为，以及聚合物的电子变化转移现象的准备。Furthermore，我们研究了聚合物协调化学的基本基本方面。

As a new synthetic method of electrically conducting heterocyclic polymers having piーconjugation system along the polymer chain, we have developed dehalogenation polycondensation of dihaloaromatic compounds with zeroーvalent nickel complexes. (n X-ArーX + n Ni(0)Lm ーーーーー> (Ar)_n + n NiX_2Lm ; Ar : heteroaromatic unit).For example, reactions of zeroーvalent nickel complexes ( e. g., a mixture of dis (1, 5ーcyclooctadiene) nickel(0), Ni(cod)_2, and 2, 2'ーbipyridine ) with 3-alkylー2-, 5-diiodothiophene led to polycodensation to give poly (3-alkyー2, 5-thienylene) (PRTh) with molecular weight of about 15000 - 150000. PRTH was soluble in chloroform and took a random coil conformation in chloroform solution. The film of PRTh was cast on a platinum plate electrode from the chloroform solution. The electrochemical oxidation (anion doping) of PRTh in a solution containing electrolytes was accompanied by color change of the film from yellow to blue, and the color change was reversible. This observation indicates that PRTh can be used in an electronic devise.PiーConjugated copolymer, which was constituted of electronーaccepting 2, 5-thienylene ring and electronーdonating 2.5ーpyridine ring, was prepared by using zeroーvalent nickel complexes. Owing to its unique electronic structure, the copolymer shows stabilized electrochemically oxidized state. Besides the above mentioned polymers, we have studied preparation of other electrically conducting piーconjugated polymers, redox behavior of the polymers, and the electron change transfer phenomena of the polymers. Furthermore, we investigated basic basic aspects of coordination chemistry the preparation of polymers.
