摘　　要：以多金属氧酸盐(POMs)中的[Mo_(4)O_(10)(CH_(3)O)_(6)]^(2-)为无机建筑块、1,2-双(二苯基膦)乙烷(DPPE)为有机配体、硝酸银为银源,采用溶剂热法和常规合成法相结合的合成方法,通过自组装的方式制备了一种新的有机-无机杂化材料[Ag(DPPE)_(2)]_(2)[Mo_(4)O_(10)(CH_(3)O)_(6)]•2CH_(3)OH(1)。X-射线单晶衍射分析结果表明,化合物1是由同多阴离子[Mo_(4)O_(10)(CH_(3)O)_(6)]^(2-)和[Ag(DPPE)_(2)]^(+)阳离子单元通过静电作用结合而形成的。此外,对化合物1进行了X-射线粉末衍射、傅里叶红外光谱等结构分析,并通过热重分析确定其稳定性,通过固体紫外-可见漫反射测试了其禁带宽度以及甲醇溶液中的荧光光谱。结果表明,化合物1具有良好的光电流响应特性。A novel organic-inorganic hybrid material[Ag(DPPE)_(2)]_(2)[Mo_(4)O_(10)(CH_(3)O)_(6)]•2CH_(3)OH(1)has been prepared by using[Mo_(4)O_(10)(CH_(3)O)_(6)]^(2-)in polyoxometalate(POMs)as inorganic building block,1,2-bis(diphenylphosphine)ethane(DPPE)as an organic ligand and silver nitrate as a silver source,through the means of a combination of solvothermal and conventional synthesis and via the self-assembly process.X-ray single crystal diffraction analysis shows that compound 1 is formed by electrostatic interaction with polyanion[Mo_(4)O_(10)(CH_(3)O)_(6)]^(2-)and[Ag(DPPE)_(2)]^(+)cationic units.In addition,the structure of the compound was analyzed by X-ray powder diffraction and fourier transform infrared spectroscopy.The stability was determined by thermogravimetric analysis,the band gap was determined by solid UV-visible diffuse reflection test,and the fluorescence spectra in methanol solution were measured.It was found that compound 1 showed good photocurrent response.
