To achieve highly stable electrochromic materials, 4,5-bis(2-/3-thiophenyl)-1,2-dialkoxybenzene precursors were prepd., cyclized (aromatized), and the resulting naphthodithiophene monomers were subjected to oxidative polymn. (chem. as well as electrochem.). The precursors, monomers, and polymers were characterized by spectroscopic and electrochem. methods. [on SciFinder(R)]
