Mechanically linked poly[2]rotaxanes constructed from the benzo-21-crown-7/secondary ammonium salt recognition motif†
Abstract
Mechanically linked poly[2]rotaxanes have been designed and synthesized on the basis of the benzo-21-crown-7/secondary ammonium salt recognition motif, which displays interesting thermal and rheological properties due to the integration of [2]rotaxane moieties into the polycaprolactone chains.
