In the Communication “Block-Selected Molecular Recognition and Formation of Polypseudorotaxanes between Poly(propylene oxide)-Poly(ethylene oxide)-Poly(propylene oxide) Triblock Copolymers and α-Cyclodextrin” by J. Li, X. Ni, and K. Leong (1), the authors neglected to cross-reference their thematically related full article in J. Am. Chem. Soc. 2003, 125, 1788–1795 by J. Li, X. Ni, Z. Zhou, and K. Leong. The later full article reported the strong evidence for the formation of the triblock copolymer architectures, as well as details of the preparation and characterization of the polypseudorotaxanes. The authors apologize for this oversight.
