摘要 以[(η5-C5Me5)2Mo2(μ-S)2S2]和Cu(MeCN)4(ClO4)在乙腈中回流并与PPh3反应得到了簇合物[(η5-C5Me5)2Mo2(μ3-S)4Cu2(PPh3)2](ClO4)2·H2O.对其进行了红外、紫外光谱和X射线晶体结构测试.并使用Z扫描技术在532nm处测定了其在CH2Cl2溶液中的三阶非线性光学(NLO)性质.结果表明:该簇合物具有立方烷结构的簇阳离子,在溶液中表现出较强的三阶非线性吸收和自散焦效应. The reaction of [(η5-C5Me5)2Mo2(μ-S)2S2] and Cu(MeCN)4(ClO4) by refluxing in MeCN followed by addition of PPh3 resulted in cluster [(η5-C5Me5)2Mo2(μ3-S)4Cu2(PPh3)2](ClO4)2·H2O.The product was characterized by IR, UV-vis spectra and single-crystal X-ray crystallography. The third-order nonlinear optical (NLO) properties were measured in CH2Cl2 solution by Z-scan technical at 532 nm. This cluster has a cubane-like cation, which shows strong third-order NLO absorption effects and self-defocusing properties.
