electrochromic

The ability of a material to transmit light due to a change in electrical current. The optical properties are reversible, and the material reverts to its original state once the electrical current is removed. As such, electrochromic materials are the primary choice for visual devices, such as smart windows, light shutters, information displays, reflectance mirrors, and thermal radiators. In green architecture, electro-chromic materials are mainly used in “smart windows” for their energy efficiency and thermal comfort. The transparency/opacity level is adjusted by an applied voltage.

They studied their complexes with various metal ions and reported visible electrochromism for ruthenium-bipyridine complexes [11].
Electrochromism is a reversible and visible change in the transmittance and/or reflectance of a material by electrochemical oxidation or reduction.
Studies of the molecular mechanisms that result in potential-dependent optical properties have produced evidence supporting three mechanisms (for different dyes): dipole rotation, electrochromism, and a potential-sensitive monomer-dimer equilibrium.
Unlike inorganic compounds, intrinsically conducting polymers are more attractive electrochromic materials because of their relatively low-optical switch potentials, fast response, and colorful electrochromism (3), (4).
