WebA series of chiral cyclic dyads, axially chiral binaphthyls linked to a 3,3′-bipyridyl, was synthesized. The dyad 2bearing methoxy groups exhibited ON/OFF properties in circularly polarized luminescence (CPL), yielding a glum of 1.6 × 10–3or 0 without any change in fluorescence. This type of CPL switch is unprecedented. flamecharm cloakWebA chiral switch is a chiral drug that has already approved as racemate but has been re-developed as a single enantiomer.
