Photochromic process : Organoboron‐functionalized 1,2‐dithienylcyclopentene shows photochromism. Its absorption spectra can be modulated by fluoride and mercuric ions. The maximum of the photostationary state shifts from 560 to 490 nm upon the addition of fluoride anions and to 450 nm upon the addition of mercuric cations. The modulation mechanism is investigated.
