文摘

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 ¹H and ¹³C NMR spectra associated with the dithiocarbamate ligands. IR and ¹³C NMR spectral studies indicate that the S₂CN double bond character increases with increase in length of alkyl chain bonded to nitrogen atom. Bis(N-benzyl-N-(2-phenylethyl)dithiocarbamato-S,S¡ä)lead(II) (3) and bis(N-furfuryl-N-(2-phenylethyl)dithiocarbamato-S,S¡ä)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.
