Photo- and Redox-active Benzofuran-appended Triphenylamine and Near-infrared Absorption of Its Radical Cation

A triarylamine bearing three benzofuran rings was designed and successfully prepared in 64% yield. It exhibited absorption at 385 nm, and blue emission at around 440nm with a fluorescence quantum yield of 0.57. This compound showed high heat resistance and reversible one-electron oxidation. Upon one...

Summary:A triarylamine bearing three benzofuran rings was designed and successfully prepared in 64% yield. It exhibited absorption at 385 nm, and blue emission at around 440nm with a fluorescence quantum yield of 0.57. This compound showed high heat resistance and reversible one-electron oxidation. Upon one-electron chemical oxidation, a near-infrared absorption was revealed due to a persistent radical cation species. DFT calculations also supported the experimental data.
