Simultaneous fluorescence and redox modulation in an irreversible photochrome based on a strained dibenzo-acridinium cation.
A highly strained non-luminescent dibenzo-acridinium cationic compound is identified that undergoes in acetonitrile light-induced ring closure to create a highly fluorescent, planar, eight-ringed cationic anti-aromatic dye.
