摘要:
在氮气氛下,采用配体取代法,即以C60取代Pd(Ph2PCH2PPh2)2中一个Ph2PCH2PPh2合成出富勒烯金属配合物C60Pd(Ph2PCH2PPh2),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/H2Q介质电对中,光生电压最大达到174 mV;当C60Pd(Ph2PCH2PPh2)薄膜厚度为1 μm时,光伏效应值最大.

Abstract:
Fulerene complexe C60 Pd( Ph2PCH2PPh2)was perpared by the method of ligand substitution via the reaction of C60 with Pd(Ph2PCH2PPh2)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 Ph2PCH2PPh2 took up two coordination sites of the central metal,and C60 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 C60Pd(Ph2PCH2PPh2)/ GaAs was supper,especially in the BQ/ H2Q redox couple,and the greatest value of photovoltaic potential was up to 174 mV. The photovoltaic performance of C60Pd(Ph2PCH2PPh2)/GaAs electrode at 1 μm for thickness of C60Pd(Ph2PCH2PPh2)film was the best.
