The mono‐ and bis‐reduction of 6,13‐bis((triisopropylsilyl)ethynyl)quinoxalino[2,3‐ b ]phenazine ( 1 ) with potassium anthracenide in THF is reported. Both the radical anion 1 .− and the dianion 1 2− were isolated and characterized by optical and structural (single‐crystal X‐ray diffraction) methods. Solutions of the radical anion 1 . − were stable in air for several hours and characterized by EPR spectroscopy. Dianion 1 2− is highly fluorescent and photostable.
