成功合成了有机硼基二芳基乙烯，并显示出光致变色性能。此外，它的光致变色性能可以通过氟离子来调节。加入氟离子后，光稳态的最大吸收从655 nm移至490 nm。其调制机理是由于三价硼原子与氟离子之间特殊的刘易斯酸碱相互作用。
Organoboron-based diarylethene was successfully synthesized and exhibited photochromic property. Furthermore, its photochromic property can be modulated by a fluoride ion. The absorption maximum of the photostationary state shifted from 655 to 490 nm upon addition of a fluoride ion. The modulation mechanism is attributed to the special Lewis acid-base interaction between a trivalent boron atom and a fluoride ion.
