Zhou, Zhiguo published the artcilePhotochromic organoboron-based dithienylcyclopentene modulated by fluoride and mercuric(II) ions, Product Details of C15H14Cl2S2, the publication is ChemPhysChem (2007), 8(9), 1289-1292, database is CAplus and MEDLINE.
Organoboron-functionalized 1,2-dithienylcyclopentene [1-(5-chloro-2-methylthien-3-yl)-2-[5-(dimesitylboryl)-2-methylthien-3-yl]cyclopentene] was prepared, characterized by x-ray crystallog., et al. and found to show photochromism (via photocyclization). 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 was studied.
