摘 要:采用水热合成方法得到1个Fe(Ⅲ)配合物{[Fe(phen)3][Fe(CN)6]·0.5phen·5H2O}(phen=1,10-菲啰啉).通过红外光谱(IR)、紫外可见吸收光谱(UV-Vis)、X射线粉末衍射(XRD)、X射线单晶衍射和表面光电压谱(SPS)对其进行了表征和光物理性质测定.结构解析结果表明,标题配合物是1个以Fe(Ⅲ)为中心的离子型配合物,配阴、阳离子分别是[Fe(CN)6]^3-和[Fe(phen)3]^3+.丰富而复杂的分子间氢键最终将分子连成了3D网状结构.采用表面光电压谱(SPS)和场诱导表面光电压谱(FISPS)探讨了配合物的表面光电性能.结果表明,它在紫外-可见光(λ=300-800nm)诱导下,呈现出明显的表面光伏响应,表明其具有一定的光-电转换能力.同时对配合物的UV-Vis吸收光谱和IR光谱进行了分析和指认.A Fe( Ⅲ ) complex {[Fe(phen)3][Fe(CN)6]·0.5phen · 5H2O} (phen= 1,10-phenanthroline) has been synthesized by the hydrothermal method and characterized by the IR, UV-Vis absorption spectra, X ray powder diffraction(XRD), X ray single crystal diffraction and surface photovoltage spectroscopy(SPS). The structural analysis shows that the title complex is a Fe( Ⅲ) ionic complex with cation of [Fe(phen)3]^3+ and anion of [Fe(CN)6]^3-. By the intermolecular hydrogen bonding interaction, the molecules are networked into a 3D structure. The photoelectric property was investigated by surface photovoltage spectroscopy (SPS) and field-induced spectroscopy surface photovoltage(FISPS). The results show that the complex exhibits positive surface photovoltage response under the inducement of UV-Vis light (λ=300-800 nm), indicating that it possesses certain photoelectric conversion properties. In addition, the UV-Vis and IR spectra of the complex were analyzed and assigned.
