Redox‐Activated Near Infrared/Shortwave Infrared Emissive Chromophores: Synthesis of Triphenylamine‐Appended Pyrazinacenes

open access: yesAngewandte Chemie International Edition, EarlyView.
Redox‐active triphenylamine‐appended pyrazinacenes show extreme reversible redox‐coupled switching of their photophysical properties. In their reduced state, absorption and emission bands fall well within the visible region. Oxidation results in a shift in the absorption and fluorescence bands to the near infrared and short‐wave infrared regions while ...
