LCST-type polymers based on chiral-polymeric ionic liquids [PDF]

Chemical Communications, 2014
The self-assembly of linear polymers containing chiral IL units generates a high-order supramacromolecular structure with a complex hierarchical architecture, which is able to exhibit thermoresponsive behavior (lower critical solution temperature: LCST) with different structural elements that can be used to fine tune this LCST.
