Conformational changes and chiroptical switching of enantiopure bis-helicenic terpyridine upon Zn(2+) binding

Chem Commun (Camb). 2016 May 1;52(35):5932-5. doi: 10.1039/c6cc01748g. Epub 2016 Apr 7.

Abstract

The molecular conformation of a bis-helicenic terpyridine system is strongly modified upon binding to Zn(ii) ion, a process that is accompanied by large changes in the optical and chiroptical properties. This system affords a new type of helicene-based chiroptical switching.
