Nine lead bis(dithiocarbamate) complexes based on benzyl and furfuryl groups have been prepared. The complexes were characterized using IR and NMR spectroscopy. All the complexes showed the expected signals in (1)H and (13)C NMR spectra associated with the dithiocarbamate ligands. IR and (13)C NMR spectral studies indicate that the S(2)CN double bond character increases with increase in length of alkyl chain bonded to nitrogen atom. Bis(N-benzyl-N-(2-phenylethyl)dithiocarbamato-S,S')lead(II) (3) and bis(N-furfuryl-N-(2-phenylethyl)dithiocarbamato-S,S')lead(II) (4) have been used as single source precursors for the synthesis of ethylenediamine capped PbS nanoparticles. Powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), FTIR, UV-vis and fluorescence spectroscopy have been used to characterize the as-prepared lead sulfide nanoparticles. The PXRD measurements suggest that PbS nanoparticles are single phase with face-centered-cubic structure.
已经制备了基于苄基和糠基的九种双（二硫代氨基甲酸盐）配合物。使用 IR 和 NMR 光谱对配合物进行了表征。所有配合物在（1）H 和（13）C NMR 光谱中均显示出与二硫代氨基甲酸盐配体相关的预期信号。IR 和（13）C NMR 光谱研究表明，随着与氮原子键合的烷基链长度的增加，S(2)CN 双键的特征增加。双（N-苄基-N-（2-苯乙基）二硫代氨基甲酸盐-S，S'）铅（II）（3）和双（N-糠基-N-（2-苯乙基）二硫代氨基甲酸盐-S，S'）铅（II）（4）已被用作合成乙二胺封端的 PbS 纳米粒子的单源前体。使用粉末 X 射线衍射（PXRD）、扫描电子显微镜（SEM）、FTIR、UV-vis 和荧光光谱对制备的硫化铅纳米粒子进行了表征。PXRD 测量表明 PbS 纳米粒子具有面心立方结构的单相。
