Binaphthyl–Bipyridyl Cyclic Dyads as a Chiroptical Switch
No full textA series of chiral
cyclic dyads, axially chiral binaphthyls linked
to a 3,3′-bipyridyl, was synthesized. The dyad <b>2</b> bearing methoxy groups exhibited ON/OFF properties in circularly
polarized luminescence (CPL), yielding a |<i>g</i><sub>lum</sub>| of 1.6 × 10<sup>–3</sup> or 0 without any change in
fluorescence. This type of CPL switch is unprecedented. Regioisomer <b>4</b> exhibited a <i>dextro</i>/<i>levo</i> rotation switching ability in [α]<sub>D</sub>. X-ray structures
as well as experimental and theoretical analyses suggested that the
switching properties depended on conformational changes
