在氮气氛中采用配体取代法合成了富勒烯双齿膦配合物C80Pd(Ph2PCH2CH2PPh2),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,研究了产物的氧化还原性能及热稳定性能.在光电化学电池中测定了C60Pd(Ph2PCH2CH2PPh2) 在GaAs电极上形成n+n型异质结光伏效应,结果表明:产物具有优良的光电转化性能,尤其是在Fe(CN)63-/Fe(CN)64-介质电对中,光生电压最大达到367mV;当C60Pd(Ph2PCH2CH2PPh2) 薄膜厚度为1μm时,光伏效应值最大.
The fullerene bidentate phosphine complex C80Pd (Ph2PCH2CH2PPh2) was synthesized by ligand substitution method in nitrogen atmosphere. The product was characterized by elemental analysis, infrared spectroscopy, UV-Vis, photoelectron spectroscopy and X-ray powder diffraction. The redox properties and thermal stability of the products were investigated.The formation of n + n heterojunction photovoltaic effect of C60Pd (Ph2PCH2CH2PPh2) on GaAs electrode was measured in photoelectrochemical cell.The results show that the product has excellent photoelectric conversion properties, especially The maximum photovoltaic voltage reached 367mV in the Fe (CN) 63- / Fe (CN) 64-dielectric pair. When the film thickness of C60Pd (Ph2PCH2CH2PPh2) was 1μm, the photovoltaic effect was the highest.
