摘要
本文通过三种二茂铁基金属羰基簇合物的循环伏安特性,研究了金属羰基簇合物对二茂铁间电荷传递的影响.其中钴羰基簇合物对二茂铁间的电荷传递有阻断作用,而锇羰基簇对二茂铁基的电荷传递有增强作用。研究表明羰基簇与共轭炔桥的配位形式决定增强和阻断的根本原因。
In order to investigate t he effect of carbonyl metal cluster on the charge transfer between the ferrocenyl units, three carbonyl metal clusters, Co：（CO）6（Fe-C≡ C-C ≡ C-Fc）,Co4（CO）12（Fc-C≡C-C≡ C-Fc） and Os3 （CO）u （FcC≡C-C≡CFc）, were synthesized according the previous methods. The redox potential differecne of three cluster in cyclic voltammograms showed that the carbonyl metal cluster interdicted or stimulated the electron interaction of ferrocenyl units, and the interdictory and stimulative effect of carbonyl metal cluster were decided by their coordination to alkyne groups.
