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.

Thermoresponsive Polymere unterliegen einer Phasentrennung als Reaktion auf Temperaturänderungen. In ihrer Zuschrift (e202209530) stellen Simon Harrisson, Colin Bonduelle et al. die Verwendung synthetischer Polymere vor, die aus L‐Prolin‐Monomereinheiten bestehen und eine temperaturgesteuerte Aggregation in Wasser mit beispielloser Hysterese zeigen. Dieses proteinähnliche Verhalten ebnet den Weg zu neuen Prozessen, die entweder durch Temperatur‐ oder Ionenstärkeänderungen angetrieben werden, wie z. B. einfache Thermometer “mit Gedächtnis".
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
