Biocompatibility of cucurbit[n]urils

Chimica Techno Acta
This review considers the biological properties of nitrogen-containing macrocyclic glycoluryl derivatives – cucurbit[n]urils (CB[n]). Currently, the use of biomaterials that come into contact with the internal environment of the body is widespread in ...

Near‐Infrared Light‐Driven Photocatalysis: From Advanced Light‐Harvesting Architectures to Rational Reactor Design

EcoEnergy, EarlyView.
This review systematically elucidates the regulatory strategies for NIR light, encompassing macroscopic mechanisms such as band engineering, localized surface plasmon resonance (LSPR), upconversion luminescence, and photosensitizer molecules. Furthermore, it provides an in‐depth discussion on their cutting‐edge applications in energy conversion (e.g ...

Poly Schiff bases embedded polyrotaxane for flexible memristor and artificial synapses

FlexMat, EarlyView.
Solution‐processable poly Schiff base (PSB) is designed and synthesized by embedding it within cyclodextrin. The resulting memristor shows high ON/OFF ratio (107), fast switching (25 ns), excellent environmental stability (>8 months) and bendability (3 mm), and emulates synaptic plasticity and achieves image recognition.

Illuminating Streptomyces: Raman Spectroscopy for Antibiotic Detection and Monitoring

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy provides a non‐destructive, label‐free approach for studying the chemical diversity of Streptomyces. This review presents its application from detection to chemical characterization of secondary metabolites and monitoring of biosynthetic processes.

A Portal-Preorganized Cucurbit[7]uril-Ruthenium Conjugate Enables Motif-Selective Protein Sensing. [PDF]

Angew Chem Int Ed Engl
Reprogramming cucurbit[7]uril (CB7) recognition through portal engineering transforms an optically silent host into a motif‐selective photoluminescent receptor. The portal‐preorganized CB7‐Rubpy conjugate directly reports changes in aromatic motif accessibility, enabling optical sensing of protein misfolding and refolding.

Cross‐Scale Engineering of Single‐Atom Catalysts from Local Planar Coordination to Spatial Architectures

Small, EarlyView.
This Review presents a cross‐scale framework for single‐atom catalysts, spanning in‐plane and out‐of‐plane coordination; primary coordination, secondary‐sphere interactions, through‐space microenvironments and support interfaces; individual sites and macroscopic architectures; and static design and directed dynamic reconstruction.

Distinct Nanohoop Structures and Ratiometric Emissions of Isomeric DPAC‐Based Macrocycles Tuned by Nano‐Twisting of Stiff‐Stilbene Optical‐Switches

Small, EarlyView.
Tunable nano‐twisted structures of novel isomeric macrocycles, which were controlled by cis/trans isomerizations of stiff‐stilbene units under light irradiations, have been exploited to modulate bent and planar configurations of 9,14‐diphenyl‐9,14‐dihydrodibenzo[a,c]phenazine (DPAC) moieties and adjust their ratiometric emissions. External factors, i.e.

Unraveling the effect of topological structures of B/N‐doped conjugated macrocycles on spectral properties: A computational study

Smart Molecules, EarlyView.
Herein, we constructed a series of fully B‐doped, fully N‐doped and hybrid B/N‐doped conjugated macrocycles considering three key topological factors. At a fixed ring size, the spectra initially redshift then blueshift with varying B/N ratio, while ring size exhibits negligible impact on spectra.

Understanding the Dynamics of Mechanically Interlocked Molecular Systems via Metadynamics Simulations

The Chemical Record, EarlyView.
This Personal Account discusses how molecular simulations help uncover motion, shuttling mechanisms, and kinetics in mechanically interlocked molecules such as rotaxanes and catenanes. Mechanically interlocked molecules, such as rotaxanes and catenanes, display complex internal dynamics and reciprocal motions that are central to their use as artificial
