项目摘要
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.
作为一种新的合成具有沿着高分子链的π共轭体系的导电杂环聚合物的方法,我们发展了二卤代芳香化合物与零价镍配合物的脱卤缩聚反应。(nX-Ar <$X + nNi(0)Lm <$N(0)Lm <$N(0)Lm)>(Ar)_n + nNiX_2Lm; Ar:芳杂环单元)。例如,在一个实施例中,双(1,5-环辛二烯)镍(0)、Ni(cod)_2和2,2 '-联吡啶)与3-烷基-2,5-二碘噻吩的混合物导致聚编码,得到分子量约为15000 - 150000的聚(3-烷基-2,5-亚噻吩基)(PRTh)。PRTH可溶于氯仿,在氯仿溶液中呈无规卷曲构象。将PRTh的膜从氯仿溶液浇铸在铂板电极上。PRTh在含电解质溶液中的电化学氧化(阴离子掺杂)伴随着膜的颜色从黄色到蓝色的变化,并且颜色变化是可逆的。用零价镍配合物制备了由2,5-噻吩环和2.5-吡啶环组成的π-共轭共聚物,并将其应用于电子器件中。由于其独特的电子结构,共聚物显示稳定的电化学氧化态。除上述聚合物外,我们还研究了其它导电π共轭聚合物的制备、氧化还原行为和电子转移现象。此外,我们还研究了配位化学的基本方面,聚合物的制备。
