Abstract: The ionization potentials and half-wave reduction potentials of a series of a- naphthyl-and phenyl-substituted polysilanes have been determined and used to elucidate the nature of the electronic interactions between aryl and polysilanyl groups. It is shown that the relative energies of the u and a electrons have a substantial in-fluence on the energy and character of the highest occupied molecular orbital, and hence the electronic spectra ...
