Pyrazinacene dyes: A new class of redox-responsive fluorescent probes tunable for visible and infrared applications

Caption

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 maintaining high fluorescence quantum yields.
