Abstract:
Fullerene and it’s dervant have unique poperties on physics and chemistry. The main purpose of the synthesis of new type fullerene complexes is to exploit the applications of fullerene and it′s dervant as functional materials. The method of ligand substituting was employed, by which, the fullerene complexe C60Pt(CO) (Pph3) has been perpared by the reaction of C60 replacing the ligands CO and Pph3 in Pt(CO)2(Pph3)2 under a nitrogen atmosphere and refluxing. The title compound was characterized by elemental analysis, FT-IR, UV-vis, XPS. The results show that the structure of purposeful product is that the ligands CO and Pph3take up two coordination sites of the central metal, and C60take up another two sites in σ-π fee back pattern. The electron flowing power of the molecule is strong, because of super conjugation in the molecule. The complexe may have super poperties on photoelectricity and catalysis. The result of redox research indicates that the reduction potential of the complexe is more negative than that of pure C60.

摘要:
采用配体取代法,即在惰性气氛下以C60取代Pt(CO)2(Pph3)2中的CO及Pph3,合成了C60Pt(CO)(Pph3)富勒烯金属配合物,利用元素分析、红外光谱、紫外可见光谱、光电子能谱等手段对产物进行鉴定和表征,结果表明,C60以σ-π配位方式与Pt形成了稳定的η2型C60配合物.由于该分子存在超共轭作用,分子内电子流动性大,因而该配合物可能具有良好的光电转化性能及催化性能.氧化还原性能研究表明,C60在与金属有机基团Pt(CO)(Pph3)形成配合物后,其还原电位向负方向发生了移动.
