New naphthalene-sulfur compounds, oligomers of poly (l,4-naphthylene sulfide), have been synthesized and studied by electronic and vibrational spectroscopy in both pristine and oxidized forms. It has been found that the charged defects induced on these molecules are Much More stable than in the corresponding 1,4-phenylene derivatives. Nevertheless their physical properties are strongly affected by steric effects which hinder a regular arrangement of the repeating units.
