资源简介：
A series of chiral
cyclic dyads, axially chiral binaphthyls linked
to a 3,3′-bipyridyl, was synthesized. The dyad 2 bearing methoxy groups exhibited ON/OFF properties in circularly
polarized luminescence (CPL), yielding a |glum| of 1.6 × 10–3 or 0 without any change in
fluorescence. This type of CPL switch is unprecedented. Regioisomer 4 exhibited a dextro/levo rotation switching ability in [α]D. X-ray structures
as well as experimental and theoretical analyses suggested that the
switching properties depended on conformational changes.
