Article Abstract
A dynamic silver(I)-loaded [2]rotaxane shuttle ( = 135 kHz) was converted allosterically into a conformationally restricted [2]rotaxane due to the creation of a bulky imine in the center of the axle component. Only the dynamic silver(I)-loaded [2]rotaxane was able to catalyze a 6--cyclization reaction, whereas the static one was catalytically quiet. The mechanism of catalyst deactivation was elucidated.

Covalent organic frameworks (COFs) have great potential as versatile platforms for proton conduction. However, the commonly applied 2D COFs that are easy to design and synthesize have only 1D channels for proton conduction, limiting the formation of continuous hydrogen bonds due to the anisotropy between their crystalline grains. Herein, we report a strategy to construct 3D channels in 2D COFs by using rotaxane structures and eliminate the strong interlayer π-π interactions, facilitating the formation of smooth 3D proton-transfer pathways during guest doping.

Bone tissue engineering scaffolds for bone defect treatment face numerous challenges, including mechanical mismatches and the lack of immune microenvironment modulation, often leading to implant failure. In this study, an innovative drug-loaded bioinspired ceramic/polymer composite scaffold was designed and fabricated using extrusion-based 3D printing technology, incorporating α-cyclodextrin (αCD) in a novel approach to improve interfacial compatibility and drug-loading efficiency. Hydroxyapatite (HA), the main component of natural bone, was employed as the inorganic phase to mimic the mineral structure of bone tissue.

Graphene-based films are highly valued for their superior conductivity, thermal stability, and mechanical strength, yet their brittleness and low ductility limit their full potential. Current toughening strategies for graphene-based composites mainly focus on interfacial reinforcement between polymers and graphene substrates. However, research on energy dissipation arising from the intrinsic properties of polymers remains limited.

The assembly of molecular nanomachines using atomically precise manipulations promises to enable nanotechnology with unprecedented architectural features and exquisite functional properties. However, this future is critically limited by the ability to autonomously manufacture nanomachines, with current efforts being heavily labor intensive. A system is needed to program and assemble matter under digital control, unifying molecular nanotechnology and macroscale chemical processes.

Gaining insight into the dynamic behavior of supramolecular systems is essential for understanding selective guest encapsulation and for the rational design of nanodevices capable of precise, controllable motion at the molecular scale. In this work, we report the construction of a pseudo-rotaxane system through the encapsulation of a naphthalenediimide (NDI) derivative bearing long aliphatic chains within the cavity of a nanosized metallorectangle. Electrochemical studies reveal that encapsulation significantly alters the redox properties of the guest.
