| 摘要: 用室温固相反应法合成了一种具有非线性光学性质的二茂铁-多金属氧酸盐混合价化合物[Fe(C5H5)2]4PMo12O40。用元素分析、红外光谱、紫外漫反射电子光谱、穆斯堡尔谱、ESR、XRD等手段对其进行了表征和研究,确定了该化合物的组成与结构。结果表明在反应过程中杂多阴离子发生了单电子还原反应,生成了混合价化合物。非线性光学性质研究表明标题化合物的倍频效应强度为I2ω=0.4IKDP,三阶非线性光学系数为χ(3)=5.1×10-11esu。 |

| Abstract: In this paper, We report the preparation of a mixed valence compound by use of organic donor Ferrocene(FeCp2) and inorganic acceptor Keggin structure H3PMo12O40, at room temperature. The compound was characterized by elemental analysis, FTIR, XRD, reflectance spectroscopy, ESR Measurements, Mössbauer spectra and CV. The results indicate that the anions of the heteropoly acid remain unchanged in mixed valence compound formation.The nonlinear optical property measurements indicate the second harmonic generation intensity is I2ω=0.4IKDP, and the third-order susceptibility isχ(3)=5.1× 10-11esu． |
