摘要
The binuclear Pt(II) complexes bridged by thieno[3,2-b]thiophenes were prepared and their redox behavior was measured by cyclic voltammetry. The complexes showed two one-electron quasi-reversible waves and their first redox potentials are comparable with that of ferrocene. The oxidation potentials of the complexes and the related complexes are explained by the result of the MO calculation. The one-electron oxidation of some complexes gave stable oxidized complexes which showed no IT band in the near infrared region. The electronic and EPR spectra suggest that an unpaired electron is localized on the Pt atom. (C) 2002 Elsevier Science B.V. All rights reserved.
