Summary: A highly fluorescent photochromic polymer, poly‐BTFO4, was prepared. The fluorescence quantum yield of the poly‐BTFO4 was six times higher than that of BTFO4. Fatigue resistance of the polymer at its photostationary state was significantly enhanced compared with that of BTFO4. Importantly, the poly‐BTFO4 film also showed an efficient photochromism as well as strong fluorescence similar to the results in solution, which allow photoinduced fluorescence switching applicable to optical switches.Improvement of fluorescence quantum yield and fatigue resistance.
