Back Cover: Memory Effect in Thermoresponsive Proline‐based Polymers (Angew. Chem. Int. Ed. 46/2022)

Thermoresponsive polymers undergo phase separation in response to changes in temperature. In their Communication (e202209530), Simon Harrisson, Colin Bonduelle, and co-workers present the use of synthetic polymers consisting of L-proline monomer units exhibiting temperature-driven aggregation in water with unprecedented hysteresis. This protein-like behavior paves the way to new processes, driven by either temperature or ionic strength changes, such as simple “with memory” thermometers.
