Irreversible Organic Electrochromic Materials
Electrochromic materials change colour with an electric current and have many applications as low energy visual indicators (e.g. displays, signage, e-readers). Currently, these materials are mainly reversible. However, for security related applications (e.g. smart, anti-tampering labels), irreversible materials would be highly desirable. This innovation presents high-performing, green, manufacturing-compatible, irreversible organic electrochromic formulations.
