  Electrochemical Synthesis of Cadmium(II) Carboxylates Compounds at Sacrificial Cadmium Anode

  摘要：

  以镉和铂分别作为阳极和阴极，四丁基氯化铵作为支持电解质，在不同的羧酸（RCOOH）存在下，采用电化学技术合成了羧酸镉及其配位化合物。阳极镉在乙腈溶液中与不同的羧酸或 1,10-菲咯啉 (phen) 和 2,2'-联吡啶 (bipy) 进行电化学氧化，产生配合物 Cd(OOCR)2 和 Cd(OOCR)2L (L = phen 或 bipy），分别。光谱研究、FTIR、元素分析和物理测量的结果证实了不同羧酸的羧酸盐基团与镉之间存在键合。还讨论了所有这些合成化合物的当前效率。

  Correlation of CdS Nanocrystal Formation with Elemental Sulfur Activation and Its Implication in Synthetic Development

  摘要：

  Formation of CdS nanocrystals in the classic approach (with octadecene (ODE) as the solvent and elemental sulfur and cadmium carboxylate as the precursors) was found to be kinetically dependent on reduction of elemental sulfur by ODE, which possessed a critical temperature (similar to 180 degrees C). After elemental sulfur was activated by ODE, the formation reaction of CdS followed closely. 2-tetradecylthiophene from the activation of S by ODE and fatty acids from the formation reaction of CdS were found to be the only soluble side products. The overall reaction stoichiometry further suggested that oxidation of each ODE molecule generated two molecules of H(2)S, which in turn reacted with two molecules of cadmium carboxylate molecules to yield two CdS molecular units and four molecules of fatty acids. In comparison to alkanes, octadecene was found to be substantially more active as a reductant for elemental sulfur. To the best of our knowledge, this is the first example of quantitative correlation between chemical reactions and formation of high-quality nanocrystals under synthetic conditions. To demonstrate the importance of such discovery, we designed two independent and simplified synthetic approaches for synthesis of CdS nanocrystals. One approach with its reaction temperature at the critical temperature of S activation (180 degrees C) used the same reactant composition as the classic approach but without any hot injection. The other approach performed at an ordinary laboratory temperature (<= 100 degrees C) and in a common organic solvent (toluene) was achieved by addition of fatty amine as activation reagent of elemental sulfur.

  Phase equilibria in the binary systems of cobalt(II) caprylate with a divalent metal (lead, cadmium, or zinc) caprylate were studied by differential thermal analysis and polarization microscopy, and the concentration and temperature ranges of the existence of liquid crystals and glasses were determined. Continuous or boundary smectic liquid-crystal solutions were found to form in all the systems. The temperature and concentration dependences of the electronic absorption spectra of liquid crystals and glasses in binary systems based on cobalt caprylate were investigated.
