Paragraph 0016; 0034; 0043, (2017/07/20)
The invention discloses [1-[2-methyl-3-benzothiophene], 2-(2-methyl-5-(4-phenyl)-(2-benzoylquinoline-8-benzothiazolyl)-3-thienyl)] octafluorocyclopentene, a preparation method and an application thereof. The preparation method comprises the following steps: by taking benzothiophene as a raw material, replacing by methyl iodide and bromizing and then reacting with octafluorocyclopentene, thereby generating mono-substituted octafluorocyclopentene; by taking 2-thiotolene as a raw material, bromizing and causing n-butyllithium to react with tributyl borate; connecting aldehyde-terminated benzene with thiophene ring through Stuzki coupling; protecting by adopting ethylene glycol and then reacting with the mono-substituted octafluorocyclopentene; reducing into alcoholic hydroxyl group and becoming methylene-containing bromine; reacting with 8-hydroxyquinoline-2-aldehyde group; and finally reacting with 2-amino thiophenol, thereby acquiring a target compound. The compound prepared according to the invention can be used for continuously detecting specific ions and amino acid and has an excellent selectivity.

supporting information; experimental part, p. 1018 - 1026 (2012/08/28)
Three new isomeric asymmetric diarylethenes with a naphthyl moiety and a formyl group at the para, meta or ortho position of the terminal benzene ring were synthesized. Their photochromism, fluorescent-switch, and electrochemical properties were investiga
