【摘要】 采用还原取代法合成了配合物C60Ru(dppe),通过元素分析、红外光谱、紫外-可见光谱、X射线光电子能谱和X射线多晶粉末衍射等多种手段对配合物进行表征,并研究了配合物的氧化还原性能.结果表明,C60以碳碳6 6双键与Ru配位形成稳定的2η型配合物;氧化还原性能研究表明,C60与金属有机基团形成配合物后,其还原电位向负方向发生了移动.

【Abstract】 In the structure of C60 molecule,there are two distinct types of C-C bonds in which the bond at 66 ring junctions are shorter and behave as olefin unit.So the metal ion can easily coordinate to them in a η2-fashion.Hyperconjugation effect lies in fullerene metal complexes,which makes the electrons flow easier in the large scope.Therefore,the complex shows promising properties in photoelectric and catalysis aspects.In the present work,we chose Ru as the central metal of complex.The fullerene complex C60Ru(dppe) was prepared by the method of reduction and substitution via the reaction of C60 with the reductive product of Ru(dppe)2Cl2,with NaBH4 as reducing agent under the conditions of a nitrogen atmosphere and refluxing.The synthesized complex was characterized by methods of elemental analysis,infrared spectra,UV-vis electronic spectra,X-ray photoelectron spectra,X-ray diffraction spectra,etc.In addition,the oxidation and reduction properties of the complex was studied by cyclic voltammetry.The result of the redox study indicates that the reduction potential of the complex is more negative than that of pure C60.
