Abstract:

Application of a voltage across a thin film of a rod coil copolymer containing 2-2- hydroxyphenylbenzothiazole in the backbone induces a reversible intramolecular proton transfer. The observed electroluminescence occurs from the excited keto form, produced electrically by a chemical reaction termed electrically generated intramolecular proton transfer, EGIPT. Stimulated emission between 540-640 nm was observed by Ps transient absorption spectroscopy. EGIPT and related proton transfer electroluminescence have implications for understanding proton transfer reactions and organic light emitting devices.
