Dynamic artificial light-harvesting systems based on rotaxane dendrimers
Although the preparation of artificial light-harvesting systems (ALHs) has attracted increasing attention, dynamic regulation of antenna effect in ALHs has been still a major challenge.

Breaking the toughness-strength trade-off in polymer nanocomposites via a mechanically interlocked interface [PDF]
Polymer nanocomposites face a fundamental challenge in simultaneously enhancing strength and toughness, as current methods often compromise one for the other. To address this issue, we have incorporated mechanically interlocked [2]rotaxane units into the

Effect of a photoswitchable rotaxane on membrane permeabilization across lipid compositions [PDF]
This study investigated a rotaxane featuring azobenzene photoswitches in its macrocycle and its ability to modulate membrane permeability in large unilamellar vesicles (LUVs) of varying lipid compositions.

A Piston-Rotaxane with Two Potential Stripes: Force Transitions and Yield Stresses
We examine a rod piston-rotaxane system, where the positions of several mobile rings on the axle are controlled by an external force acting on one of the rings. This allows us to access the translational entropy of the rings.

Mechanical Susceptibility of a Rotaxane [PDF]
We have investigated the mechanical dissociation of an ammonium/crown ether rotaxane using experimental (sonication) and computational (CoGEF) methods and found that it breaks faster than its noninterlocked or uncoupled interlocked (i.e., pulled from both sides of the axle) counterparts.

Asymmetric rotaxanes as dual-modality supramolecular imaging agents for targeting cancer biomarkers
Dual-modality imaging agents featuring both a radioactive complex for positron emission tomography (PET) and a fluorophore for optical fluorescence imaging (OFI) are crucial tools for reinforcing clinical diagnosis and intraoperative surgeries. We report

Functional Rotaxanes in Catalysis
AbstractMechanically interlocked molecules (MIMs) have gained attention in the field of catalysis due to their unique molecular properties. Central to MIMs, rotaxanes are highly promising and attractive supramolecular catalysts due to their unique three‐dimensional structures and the flexibility of their subcomponents. This Minireview discusses the use

The complexity of rotaxane dendrimers poses a great synthetic challenge and the synthesis of higher generation rotaxane dendrimers has therefore rarely been reported. Here the authors report the synthesis of acid-base switchable rotaxane dendrimers up to
