摘要: 利用模板反应和亲电取代反应,合成了6种互为顺反异构体的四氮[14]轮烯合镍(Ⅱ)配合物,并用1HNMR谱进行了确证。此外,还对一系列四氮[14]轮烯合镍(Ⅱ)配合物进行了电化学研究。应用瞬态电化学方法和电化学ESR波谱对CV峰进行了讨论与归属;研究了部分大环配合物的成膜现象及成膜机理。

Abstract: Aseries of tetraaza [14] annulene nickel(Ⅱ)macrocycles,which have cis-and trans-isomers,were synthesized for the first time by the reaction of template effect and electrophilic substitution.All of them have been characterized via EA,IR,UV.1H NMRand MS.Especially the data of 1H NMRspectra demonstrate that the two isomers really exist.In addition,the electrochemical behavior of the above compounds,together with another series of tetraaza[14]annulene nickel(Ⅱ)complexes,have been studied.We draw the conclusions of the CVpeaks by using the transient and ESRelectrochelnical methods, discussed the mechanism of forming films on the electrode surface by electropolymerization.
