✦ Synopsis

We report the first twephoton excited fluorescence excitation spectra for polysilanes in solution, film, and low temperature glass. We discuss band-teband and exciton models for the optical excitations, in order to explain a strong two-photon resonance 0.9 eV above the first absorption band.
