Abstract

The electronic structure of a one-dimensional metal complex, bis(dimethylglyoximato)platinum(II), was investigated by measurements of photoconductivity and electroabsorption (EA). The EA spectrum exhibited a large oscillatory signal just above the excitonic absorption band. The position of the oscillatory EA signal was located near the onset of the photoconductivity, and the oscillation profile showed field-dependent broadening. These features can be explained as the characteristics of the Franz-Keldysh (FK) effect. The oscillatory EA signal is reproducible by a numerical calculation of the FK effect, in which the effect of the one-dimensionality of this electronic system is taken into account.
