Front Cover: Enhanced Host‐Guest Association and Fluorescence in Copolymers from Copper Salphen Complexes by Supramolecular Internalization of Anions (ChemPlusChem 3/2023)

Abstract

The cover picture shows a fluorescent Cu-Salphen host crystal structure interacting with an anion guest pink sphere that emits in the yellow-green region represented by fireflies, as well as the counterparts linked to a polymer chain represented as a blue ribbon, which yields blue-shifted hyperchromic cyan luminescence due to the protection from its coil conformation. They emerge from the UNESCO's World Heritage Site Central University City Campus of the National Autonomous University of Mexico. More information can be found in the Research Article by G. Zelada-Guillén, M. V. Escárcega-Bobadilla, and co-workers.
