fluorescent photochromic diarylethene that can be activated
by irradiation with 405 nm light was synthesized. The turn-on mode
switching of fluorescence with visible light is favorable for application
to biological systems. The fluorescence quantum yield of the photogenerated
closed-ring isomer was as high as 0.8 in less or medium polar solvents,
and even in polar acetonitrile the yield was higher than 0.6.
