Abstract: ELECTROCHROMIC DISPLAY DEVICES COMPRISING SUBSTITUTED FLUORENE COMPOUNDS Electrochromic display devices having very desirable stability and reversibility are obtained using as the oxidant certain fluorene compounds substituted with at least two alkoxy groups per molecule. The display device comprises a reactive medium between two electrically conductive electrodes at least one of which is transparent. The reactive medium comprises an anhydrous solvent and an oxidant/reductant pair.
