英文摘要	在室温酸性条件下,利用高负电性的表面分布有20个{Mo9O9}型纳米孔道的无机富勒烯囊状阴离子 [{(MoⅥ)MoⅥ5O21(H2O)6}12{MoⅤ2O4(SO4)} 30]72- 与胍基乙酸反应,得到了表面分布有20个{Mo6O6}型纳米孔道的由102个Mo及氧原子组成的[{(Mo)Mo5O21(H2O)4SO4}12{MoⅤO(H2O)}30]12- 小无机富勒烯囊状阴离子.通过单晶X射线衍射、元素分析、FTIR、UV-Vis、TG-DTA、ESR等手段对其进行了表征.该化合物属于三斜晶系,P1空间群,晶胞参数 a=2.5377(5) nm,b=2.5932(5) nm,c=3.9547(8) nm,α=83.58(3)°,β=86.15(3)°,γ=75.55(3)°,V=25.023(9)nm3.利用脉冲时间为5 ns的532 nm激光通过Z-扫描实验得到该化合物的三阶非线性折射率γ=-3.29×10-18m2/W,三阶非线性极化率χ(3)=-1.04×10-23 m 2·V-2,表明该化合物具有较强的自散焦三阶非线性光学效应.; A small spherical inorganic fullerene nano-capsule anion of a formula [{Mo)Mo(5)P(21)(H(2)O)(4)center dot SO(4)}(12){Mo(V)O(H(2)O)}(30)](12-) bearing 20 {Mo(6)O(6)}-type rings/channels built up from 102 Mo atoms and O atoms were synthesized by reacting a highly charged spherical inorganic fullerene nano-capsule anion with the formula [{(Mo(VI))Mo(5)(VI)O(21)(H(2)O)(6)}(12){Mo(2)(V)O(4)(SO(4))}(30)](72-) bearing 20 {Mo(9)O(9)} -type rings/channels with guanidineacetic acid under, acidic conditions at room temperature. The crystal structure of the resulted compound were characterized by X-ray single-crystal diffraction, elemental analysis, TG-DTA analysis and FTIR, UV-Vis, and ESR spectrascopies. It crystallizes in a triclinic system space group P1, a = 2.5377 (5) nm, b = 2.5932(5) nm, C = 3.9547 (8) nm, alpha = 83.58 (3) degrees, beta = 86.15 (3) degrees, gamma = 75.55 (3) degrees, V = 25.023(9) nm(3). Meanwhile, its third-order nonlinear optical properties were studied using Z-scan technique with 5 ns laser pulse at lambda = 532 nm. The third-order nonlinear refractive index of the title compound is determined to be gamma = -3.29 X 10(-18) m(2)/W and the third-order nonlinear susceptibility chi((3)) = -1.04 x 10(-23) m(2).V(-2), showing strong nonlinear self-defocusing refractive effects.; 国家自然科学基金; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000258092900002&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 2; 7; 1299-1303; 29
