  “Donor–Acceptor” Oligogermanes: Synthesis, Structure, and Electronic Properties

  摘要：

  A series of oligogermanes, (Me3Si)(3)GeGeCl3, (C6F5)(3)GeGePh3, (C6F5)(3)GeGe(p-Tol)(3), and (C6F5)(2)Ge[Ge(p-Tol)(3)](2), containing substituents with different electronic properties at neighboring germanium atoms were synthesized. According to X-ray diffraction studies, UV/visible spectroscopy, and quantum chemical calculations, these "donor-acceptor" oligogermanes are characterized by energies of electronic transitions lower than those for other similar compounds.

  The preparation and some properties of the compounds (C6F5)nSiPh4−n (where n = 1–4) and (C6F5)nPh3−nSiX (where n = 1 or 2 and X = H or Cl) are described. In general, these compounds were obtained by the reaction of a (pentafluorophenyl)-metallic compound with the corresponding chlorosilane. However, compounds of the form (C6F5)nPh3−nSiCl could not be obtained in this manner; they were prepared by the
