✦ Synopsis

First examples of new, modular, redox switchable ionophores for heavy and transition metal cations are presented. These systems are based on a crown ether or polyethylene glycol unit substituted by the 1,2,4-thiadiazole/iminoylthiourea redox system (2a؊4a, 2b؊4b). The syntheses via a Boulton-Katritzki rearrangement are described and their cation
