Some molecules occur in two versions related to each other like mirror images; this property is called chirality. For example, helical polymers are chiral - they can be either left- or right-handed helices. The left and right versions differ in their optical properties, such as their optical activity (they twist the plane of polarized light in opposite directions). Molecules whose optical properties can be precisely controlled - and switched - are highly sought after, as they present interesting possibilities for new data storage devices, optical components, or liquid-crystal displays. American researchers have now developed a helical polymer with side groups that can be flipped back and forth synchronously, like Venetian blinds.
