Electrochemical photoluminescence modulation of functional materials and their electrochemical devices

This paper describes overview of electrofluorochromism, which is a phenomenon that controls photoluminescence through a change in the redox states of functional molecules, metal complexes, polymeric films, etc. Electrofluorochromic materials are considered prospective innovative materials because they can convert electrical input into intuitive visual signals. This field opens novel systems by combining absorption, reflection, and luminescence properties, leading to high contrast, night and day visibility, low-cost displays, and various sensing applications. The former sections provided a short overview of the electrofluorochromic phenomena and observation setups. The electrofluorochromic reactions and devices synchronized with the absorption change based on the electrochemical reaction we reported were also reviewed.
