DOI: 10.1021/jacs.4c05953

Abstract: We report the synthesis of a right-handed (Δ-stereochemistry of strand crossings) trefoil knot from a single molecular strand containing three pyrazine-2,5-dicarboxamide units adjacent to point-chiral centers and six pyridine moieties. The oligomeric ligand strand folds… read more here.

DOI: 10.1038/s41467-023-44302-y

Abstract: The synthesis of molecular knots remains challenging. Here, the authors report the synthesis of a chiral molecular trefoil metallaknot by self-assembly which contains only 54 atoms in the backbone. Molecular knots, whose synthesis presents many… read more here.

DOI: 10.1039/d0sc02733b

Abstract: The synthesis of complicated supramolecular architectures and the study of their reversible structural transformations remains a fascinating challenge in the field of supramolecular chemistry. Herein, two types of novel coordination compounds, a non-intertwined ring-in-ring assembly… read more here.

DOI: 10.3390/polym14061164

Abstract: With combining multi-particle collision dynamics (MPCD) for the solvent and molecular dynamics (MD) for the polymer chains, we have studied the conformation and untying behaviors of a trefoil knot polymer chain translocated through a confined… read more here.
