Timotius Sunarsa20146055DEFINITIONMaterials which changes their color reversibly when they are kept in a different electronic state CategoriesSoluble in both neutral state and electron transfer. (ex: ethyl viologen)Soluble in neutral state and form solid in electrode surface. (ex: heptyl viologen)Form solid in both neutral state and after the electron transfer. (ex: metal oxide films and conducting polymers)HOW IT WORKS
