title: Gated photochromism in triarylborane-containing dithienylethenes: a new approach to a "lock-unlock" system.
abstract: Photochromic inactive dithienylethene derivatives appended with 3- or 5-dimesitylboryl-2,2'-bithiophene have been synthesized. Upon fluoride ion-binding, the photochromic reactivity is "unlocked", displaying a novel gated photochromic property.
