以H_7[PMO_8ⅥMoO_4ⅤO_40]·12H_2O为原料与对氨基二甲苯胺(C_8H_12N_2)反应合成了一种新型杂多蓝型电荷转移配合物(C_8H_12N_2)_5H_7PMO_12O_40,并通过元素分析,IR、UV、XPS、ESR等手段对其进行了表征.发现在该化合物中杂多阴离子部分依然保持Keggin结构,还发现在多电子的杂多蓝与芳香有机物对氨基二甲苯胺之间发生了显著的电荷转移.这种电荷转移被认为是所合成的化合物具有很大三阶非线性光学性质的理论根据.利用Z-扫描技术在保持入射光强I_0=2.38×10 ̄13ω/m ̄2,波长λ=532nm条件下,测定了浓度为4.68×10(-6)mol·dm(-3)的(C_8H_12N_2)_5H_7PMo_12O_40的DMSO溶液的三阶非线性光学系数x(3),测得△Φ=-4.11,x(3)=-2.61×10(-10)esu,为当今无机、有机材料中的优秀值.
A novel heteropoly blue charge-transfer complex (C_8H_12N_2) _5H_7PMO_12O_40 was synthesized from H_7 [PMO_8MoO_4VO_40] · 12H_2O and p-aminodimethylaniline (C_8H_12N_2). Elemental analysis, IR, UV, XPS, ESR, Means to characterize it. It was found that the heteropolyanion remained Keggin structure in this compound. It was also found that there was a significant charge transfer between the multi-electron heteropoly blue and the aromatic organic compound p-aminodimethylaniline. This charge transfer is believed to be the theoretical basis for the large third-order nonlinear optical properties of the synthesized compounds. Using Z-scan technique, the concentration of 4.68 × 10 (-6) mol · dm (-3) was measured under the conditions of the incident light intensity I 0 = 2.38 × 10 ~ 13ω / m ~ 2 and wavelength λ = ), The third-order nonlinear optical coefficient x (3) of DMSO solution of (C_8H_12N_2) _5H_7PMo_12O_40 was measured. △ Φ = -4.11 and x (3) = -2.610 × 10 Inorganic, excellent value in organic materials.
