Abstract

We propose a new strategy to construct chiral molecular switches with highly reversible and sensitive chiroptical responses to variations in the external environment. Its fundamental concept involves a stimuli-triggered exchange of two conformations presenting significantly different chiroptical properties through the rotation of a carbon–carbon single bond, as demonstrated by chiral Schiff bases s-1, s-2, and a salicylamide analogue s-3.
