By the additional reaction of binuclear compounds (Me4N)2M2S4 (TDT)2 (M = Mo, W; H2TDT= H2CH3GH3S2) with mononuclear cuprous complex, two new M-Cu-S clusters Mo2 Cu2 S4 (TDT)2-(PPh3)2CH3CH2OH (1) and W2Cu2S4 (TDT)2 (PPh3 )2 · 0. 5CH3 CH2 OH·0. 5H2O (2) have been prepared and characterized by IR, UV-Vis, 31P NMR spectroscopy, cyclic voltammetry and single crystal X-ray structure analysis. Both compounds crystallize in space group P 21/ n with lattice parameters a = 1.0956(3), b = 2. 2072(3), c =2.4340(3) nm, β=100.36(2)°, V= 5.790(3) nm3 and Z = 4 for 1 and a = 1.0965(9), b = 2.2135(3), c = 2.4317(4) nm, β = 99. 63(8)°, V = 5.819(8) nm3 and Z = 4 for 2. Both molecular structures contain a cubane-like cluster core [M2Cu2S4] (M= Mo, W) and their skeletons are almost the same except for M atoms. The syntheses, structures and spectrum characterizations of these two clusters are discussed. The third-order nonlinear optical (NLO) property of the two clusters was studied by the technique of forward degenerate four-wave mixing (DFWM) for the first time and these clusters exhibited relatively large nonlinear optical coefficients.

Preconcentration/separation of Co（II）, Fe（III）, Pb（II）, Cr（IIl）, Cu（II） and Cd（II） ions using bis（5-bromo- 2-hydroxy-benzaldehyde）-2-methy1-1,5-pentane diimine （BBHBPDI） on SDS coated alumina has been reported. The influences of the analytical parameters including pH, ligand and SDS amount, type and concentration of eluent and sample volume on metal ions recoveries were investigated. At optimum values of all variables the relative standard deviation are between 2.5-2.7 and preconcentration factor was 375, while recoveries for all understudy metal ions are higher than 95%, determination limits are between 1.5-2.7. The method has been successfully applied to determination of Co（II）, Fe（III）, Pb（II）, Cr（III）, Cu（II） and Cd（II） ions content in some real samples.

对柔性电子设备日益增长的需求使得开发具有高灵敏度和高线性度的传感器更加迫切.由于拉伸应变下不可逆结构损伤诱导电阻线性急剧增加,现有的可拉伸应变传感器难以完美地同时实现这两个特性.针对这一问题,本文提出了一种兼具表面褶皱和体相梯度孔隙的新型分级互连结构,利用水热活化机制精确控制纳米级褶皱间距,通过调控相分离中热力学和动力学行为构筑出体相梯度多孔结构,通过改变器件两侧曲率实现各向异性特征,深入研究各种设计的功效、量化几何结构对灵敏度的有效贡献和追踪形态演变.基于器件显著的灵敏度和各向异性,所制备的传感器能够有效监测静态和动态位移、表面运动、二维应变信号变化以及预测液位随时间变化.本工作为实现高质量的感知能力提供了一种广泛适用、适应性强、可扩展且具有成本效益的方法.

7‐Aryl‐8H‐benzo[f]indeno[2,1‐b]quinoline‐8‐one derivatives were synthesized by means of a one‐pot condensation of 2‐naphthylamine, aromatic aldehydes, and indane‐1,3‐dione in ethanol under refluxing conditions in the presence of poly(4‐vinylpyridinium) hydrogen sulfate, a solid acid catalyst. This method has the advantages of high yield, clean reaction, simple methodology, and short reaction time. The catalyst could be recycled and reused four times without significant loss of activity. The structure of the novel compounds was confirmed by IR, 1H NMR, and 13C NMR spec-troscopy and elemental analysis.
