Supramolecular Graft Copolymerization of a Polyester by Guest‐Selective Encapsulation of a Self‐Assembled Capsule

Abstract

Repeating guest units of polyesters poly-(R)-2 were selectively encapsulated by capsule 1(BF 4 ) 4 to produce supramolecular graft polymers.The encapsulation of the guest units was confirmed by 1 HNMR spectroscopy. The graft polymer structures were confirmed by the increase in the hydrodynamic radii and the solution viscosities of the polyesters upon complexation of the capsule.A fter the capsule was formed, atomic force microscopys howed extension of the polyester chains.T he introduction of the graft chains onto poly-(R)-2 resulted in the main chain of the polymer having an M-helical morphology.The complexation of copolymers poly-[(R)-2-co-(S)-2]b ythe capsule gave rise to the unique chiral amplification knownasthe majority-rules effect.[a] Determined by size-exclusion chromatography.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: http://dx.
