合成了Ru（phen）（2）L ~（2+）型配合物，其中L为取代联吡啶家族成员，并研究了它们的光化学取代反应.在作为双齿螯合物的双苄腈衍生物的存在下，在可见光的作用下进行L的光驱逐，定量形成Ru（phen）（2）L '（2+）（L' =双腈配体）类型的新络合物。几种配合物的特征在于通过X射线晶体学。特别是，双-苄腈配合物可以结晶，并得到这些化合物的结构，包含一个13-，14-，或15-元的金属结合环，得到。通过加热Ru（phen）_2L ~（2+）与联吡啶衍生物在二甘醇中的反应，定量生成起始配合物[Ru（phen）_2L ~（2+）]。本系列化合物呈现出可有利地用于设计和构建充当光化学驱动分子机器的多组分系统的性质。
Complexes of the type Ru(phen)(2)L2+, where L is a substituted bipyridine family member, have been prepared, and their photochemical substitution reactions have been investigated. In the presence of a bis-benzonitrile derivative, acting as a bidentate chelate, photoexpulsion of L is performed under the action of visible light, with quantitative formation of new complexes of the type Ru(phen)(2)L'(2+) (L' = bis-nitrile ligand). Several complexes have been characterized by X-ray crystallography. In particular, the bis-benzonitrile complexes could be crystallized, and the structure of these compounds, containing a 13-, 14-, or 15-membered metal incorporating ring, was obtained. By heating Ru(phen)2L'2+ with a bipy derivative in refluxing ethylene glycol, quantitative formation of the starting complex [Ru(phen)2L2+] was carried out. The present series of compounds presents properties that could be profitably used in the design and construction of multicomponent systems acting as photochemically driven molecular machines.
