Abstract: Electrochromic compositions for use in devices with electrically controlled absorption of light such as light filters of variable optical density, light emission modulators, and information image displays. The described electrochromic compositions may be used, for example, for creating light-transmitting coatings of buildings for controlling indoor microclimate by regulating the flow of natural light. Specifically, described is an exemplary organic electrochromic composition that is based on biocompatible and biodegradable components and is characterized by an increased service life, a high rate of light-transmission change. The described electrochromic compositions may be prepared in a wide range of light-absorption spectra and coating colors.

Abstract: Copolymers including dioxythiophene repeating units and no acceptor units allow the formation of electrochromic polymers (ECPs) with vivid neutral state colors and very colorless oxidized states that can be switched rapidly. The dioxythiophene repeating units can included in sequences where all of one type of dioxythiophene is included exclusively as isolated dyads or triads within the copolymer, or the copolymer can be an alternating copolymer with propylenedioxythiophene units. Other non-acceptor units can be included in the copolymers. The copolymers are rendered organic solvent soluble by alkyl substituents on repeating units. The inclusion of sterically encumbered acyclic dioxythiophene (AcDOT) units promotes red color while unsubstituted ethylenedioxythiophene (EDOT) units promote blue colors, and their respective content can be manipulated to achieve a desired neutral state color. Soluble copolymers comprising at least 50% EDOT repeating units can be used in supercapacitor applications.
