Abstract

We have measured absorption spectra, luminescence spectra and the time response of luminescence intensity in σ-π conjugated polymers of silylene-biphenylene copolymers in tetrahydrofuran solution at room temperature. In order to investigate the σ-conjugated length dependence of optical properties, we have prepared the three copolymers which have different silylene chain lengths of m = 1, 2, and 6. It is found that the excitations are strongly localized at biphenylene units for m = 1 and that a strong lattice relaxation occurs for m = 2. For m = 6, the charge transfer excitation from silylene units to biphenylene units is indicated.
