Thermoreversible polymorphe Übergänge in supramolekularen Polymeren werden in der Zuschrift (e202213345) von Juan Aragó, Bartolome Soberats et al. beschrieben. Dieses Verhalten wurde bei einer neuen Familie von Squaramiden beobachtet, die sich bei Raumtemperatur zu Partikeln anordnen und beim Abkühlen der Probe eine reversible morphologische Umwandlung in Fasern erfahren. Diese Umwandlung wird durch...
Hydrogen‐bonded squaramide (SQ) supramolecular polymers exhibit uncommon thermoreversible polymorph transitions between particle‐ and fiber‐like nanostructures. SQs 1–3, with different steric bulk, self‐assemble in solution into particles (AggI) upon cooling to 298 K, and SQs 1 and 2, with only one dendronic group, show a reversible transformation into fibers (AggII) by further decreasing the temperature...
