Degradable Ureido-Polycarbonate Block Copolymers with a Complex UCST Thermoresponse. [PDF]
Macromol Rapid CommunAmphiphilic block copolymers with degradable ureido‐functionalized polycarbonate segments self‐assemble into spherical micelles in water, exhibiting an intriguing upper critical solution temperature (UCST) behavior. Upon heating, these micelles swell, collapse, and reorganize into highly hydrated condensates that mimic polymeric nanogels.

Substrate‐Selective Temperature‐Controlled Synthesis of Thiophene Derivatives at Interfaces
Angewandte Chemie, EarlyView.The deposition of a dithiophene derivative on Ag(111) at room temperature followed by annealing gives rise to molecular wires, whereas the adsorption of the same precursor on a hot substrate affords the formation of benzotrithiophene species. Abstract The temperature‐controlled transformation of organic molecules at interfaces is an incipient yet ...
