Abstract

Abstract: We report that synthetic polymers consisting of L ‐proline monomer units exhibit temperature‐driven aggregation in water with unprecedented hysteresis. This protein‐like behavior is robust and governed by the chirality of the proline units. It paves the way to new processes, driven by either temperature or ionic strength changes, such as a simple "with memory" thermometer.
