Abstract
- Preparation, IR, UV—Vis and X-ray photoelectron spectroscopy (XPS) of three molecular conductors derived from metal complexes of DMID ligand [TBA]0.6[Ni(DMID)2], [TBA]0.44][Ni(DMID)2] and TTF[TBA]0.35[Ni(DMID)2]2 are reported (DMID = 1,3-dithiolene-2-one-4,5-dithiolate, TBA = tetrabutylammonium, TTF = tetrathiafulvalene). Electronic spectra show that the characteristic π-electronic delocalization absorption band over the ligand through π—d interactions in the complexes red-shifts with the increase of oxidization degree. In addition, XPS shows that there is a characteristic ‘satellite’ peak centered at around 168.7 eV, higher by about 4.7–5.4 eV than the main peak, in the S(2p) core-level region spectra of these partially oxidized or charge transfer conductive bisdithiolene metal complexes and, furthermore, the relative intensity of the ‘satellite’ peak increases with the oxidization degree of the complexes.
