DOI: 10.1002/ejoc.202400081
Abstract: Among mechanically interlocked supramolecular systems with cyclodextrins (CDs), successful examples of CD‐based catenanes are limited compared to a number of CD rotaxanes owing to the synthetic difficulties. We herein demonstrate an efficient synthesis of a… read more here.

DOI: 10.1007/s00894-018-3830-5
Abstract: Switchable rotaxanes and catenanes are environmentally responsive mechanically interlocked molecular architectures (MIMAs). Because of their ability to exhibit reversible and controllable motion in response to environmental stimuli, switchable rotaxanes and catenanes show promise for the… read more here.

DOI: 10.1021/acs.orglett.9b04599
Abstract: A catenane consisting of two [9]cycloparaphenylenes ([9]CPPs) has been synthesized. Density functional theory calculations suggested that [n]CPPs (n = 5, 6) are highly strained upon the formation of catenanes compared with the corresponding uncatenated CPPs,… read more here.

DOI: 10.1021/jacs.0c07977
Abstract: A (FeII)6-coordinated triply interlocked (“Star of David”) [2]catenane (612 link) and a (FeII)5-coordinated pentafoil (51) knot are found to selectively transport anions across phospholipid bilayers. Allostery, topology, and building block stoichiometry all play important roles… read more here.

DOI: 10.1021/jacs.2c12027
Abstract: We have successfully constructed a chiral linear [3]catenane stereoselectively by coordination-driven self-assembly using a ditopic monodentate ligand containing l-valine residues with a binuclear half-sandwich organometallic rhodium(III) unit. Furthermore, by increasing the steric hindrance of the… read more here.

DOI: 10.1021/jacs.3c00221
Abstract: Polycatenanes are extremely attractive topological architectures on account of their high degrees of conformational freedom and multiple motion patterns of the mechanically interlocked macrocycles. However, exploitation of these peculiar structural and dynamic characteristics to develop… read more here.

DOI: 10.1021/jacs.4c10104
Abstract: Catenanes have gained increasing attention for their unique features such as topological chirality. To date, the majority of works have focused on catenanes comprising monocyclic rings. Due to the lack of efficient synthetic strategy, catenanes… read more here.

DOI: 10.1039/d0sc04317f
Abstract: We report herein the first all-donor aromatic [2]catenane formed through dynamic combinatorial chemistry, using single component libraries. The building block is a benzo[1,2-b:4,5-b′]dithiophene derivative, a π-donor molecule, with cysteine appendages that allow for disulfide exchange.… read more here.
