| 内容記述 | Electronic state properties of one-electron reduced expanded viologen compounds were investigated to develop organic molecular wires with high electro-conductivity, which are useful for constructing nano-scale electronic devices. To identify better materials than the well-studied dimethyl viologen, a prototype molecular wire component, expanded viologen compounds with internal phenyl or biphenyl groups were newly focused on. To understand the electrochemical stability of the expanded viologens, their one-electron reduced species, which are cation radicals of the expanded viologens, were studied by ESR spectroscopy and quantum chemical calculation. The optimized one-electron-reduced cation radical shows a nearly planar structure of a benzene and two pyridine rings. Calculated hyperfine coupling constants indicate that π-electrons are expanded over the three rings. Zn-reduced expanded phenyl viologen solution shows a green color and its absorption spectrum gives a clear electronic band appearing in the visible wavelength region. This visible absorption band was attributed to the electronic transition of the singly occupied electron in the free radical of the one-electronreduced expanded phenyl viologen. This assignment was confirmed by ESR measurements of the solution yielding a partially broadened spectrum. The hyperfine structure of the spectrum was examined on the basis of quantum chemical calculation results. | |||||
