Enhanced Host‐Guest Association and Fluorescence in Copolymers from Copper Salphen Complexes by Supramolecular Internalization of Anions

Invited for this month's cover are Prof. Escárcega‐Bobadilla and Prof. Zelada‐Guillén, collaborators from the National Autonomous University of Mexico (UNAM). The cover picture shows the X‐ray structure of a chartreuse fluorescent Salphen‐Cu complex that upon copolymerization receives dielectric protection from the rest of the chain in solution. This enables cyan luminescence at higher intensity via anion‐guest engulfment which renders dimmer‐like turn‐on emission. More information can be found in the Research Article by G. Zelada‐Guillén, M. V. Escárcega‐Bobadilla, and co‐workers.
