Rücktitelbild: Diastereoselective Polypseudorotaxane Formation with Planar Chiral Pillar[5]arenes via Co-crystallization Processes (Angew. Chem. 12/2025)

Abstract

Diastereoselective polypseudorotaxane formation via co-crystallization of stereodynamic planar chiral pillar[5]arene and polyethylene glycol is reported by Tomoki Ogoshi et al. in their Research Article (e202420115). In the image, the bracelet represents the polypseudorotaxane, with blue and red stones depicting the pS and pR forms of the pillar[5]arene ring, respectively. The crystals between the stones imply the crystallization method. As the number of stones increases, the possible combinations multiply, making selection more difficult, but ultimately, you will find the bracelet that suits you best.
