在氮气氛下 ,采用配体取代法 ,即以C60 取代Pd(Ph2 PCH2 PPh2 ) 2 中一个Ph2 PCH2 PPh2 合成出富勒烯金属配合物C60 Pd(Ph2 PCH2 PPh2 ) ,采用元素分析、红外光谱、紫外可见光谱、光电子能谱以及X射线粉末衍射等手段对产物进行表征 .同时研究了产物的光电性能、氧化还原性能及热稳定性能 .光伏效应研究结果表明 ,产物具有优良的光电转化性能 ,尤其是在BQ/H2 Q介质电对中 ,光生电压最大达到 174mV ;当C60 Pd(Ph2 PCH2 PPh2 )薄膜厚度为 1μm时 ,光伏效应值最大 .Fulerene complexe C_ 60Pd(Ph_2PCH_2PPh_2) was perpared by the method of ligand substitution via the reaction of C_ 60 with Pd(Ph_2PCH_2PPh_2)_2 under condition of a nitrogen atmosphere and refluxing, and the title compound was appraised and characterized by methods of elemental analysis, FT-IR, UV-vis, XPS and XRD.The results showed that the structure of purposeful product was that the Ph_2PCH_2PPh_2 took up two coordination sites of the central metal, and C_ 60 took up another two sites in σ-π feeback pattern. The porperties on photoelectricity, redox and thermostability of the title complexe were studied. The results of studying on photoelectricity showed that the photovoltaic effect of (n+n) heterojunction electrode formed by C_ 60Pd(Ph_2PCH_2PPh_2)/GaAs was supper, especially in the BQ/H_2Q redox couple, and the greatest value of photovoltaic potential was up to 174 mV. The photovoltaic performance of C_ 60Pd(Ph_2PCH_2PPh_2)/GaAs electrode at 1 μm for thickness of C_ 60Pd(Ph_2PCH_2PPh_2) film was the best.ProjectsupportedbytheNaturalScienceFoundationofFujianprovince (E0 4 10 0 0 1,E0 110 0 0 1,F0 2 10 0 10 ) ,DoctorProgramofHighterEductionofChina (980 384 10 )andSelf selectProgramofXiamenUniversity
