Abstract

original image

A fully reversible polymeric color-switch system based on reversible Diels-Alder chemistry between cyclopentadienyl capped polymers and highly electron deficient dithioesters is described. The detailed reaction progress could be mapped on a molecular level for several complete switching cycles and was underpinned by an ESI-MS study.
