Study of Electrochromism of Methoxyfluorene Compounds

Article abstract of DOI:10.1021/jo01292a030

The electrochemical and electrochromic properties of a variety of polysubstituted fluorene compounds have been studied.The 2,7- and 2,3-dimethoxy, 2,3,6,7-tetramethoxy, and 2,3,4,5,6,7-hexamethoxyfluorenes are highly reversible electrochromic materials.One-electron oxidation of these materials yields deeply colored, stable radical cations.The structure-property relationships observed for the electrochemical and absorption behavior of these materials are discussed.
