Supramolecular Allostery Achieves Tunable Luminescence Aromatic Bridged Phenothiazine Noncovalent Frameworks

Advanced Science, EarlyView.
Tunable luminescent supramolecular organic framework enabled by multiple allosteric effects, composed of a tetracation vinylphenylpyridinium‐modified aromatic‐bridged phenothiazine guest and cucurbit[8]uril, not only exhibits unique guest oxidation‐driven NIR luminescence blue‐shift and effectively enhances the quantum yield by 46‐fold to 22.2% but ...

Self‐Healing UPy‐Functionalized Polyethylene Networks: A Robust Platform for Resilient and High‐Performance Lithium Battery Separators

Advanced Science, EarlyView.
Self‐healing separators are developed by grafting ureidopyrimidinone (UPy) quadruple hydrogen‐bonding motifs onto PE‐HEMA copolymers, blended with high‐MW PEO via solvent‐free hot‐pressing. The dynamic UPy network enables autonomous healing, restoring functionality after short circuits.

Structural Deformations in Cucurbit[n]urils: Analysis, Host-Guest Dependence, and Automated Ellipticity Measurements using ElliptiCB[n] [PDF]

Cucurbit[n]urils (CB[n]s) are cyclic macrocycles with rich host-guest chemistry and can bind a variety of guests, often with high association constants. In many cases, guest binding in CB[n]s results in structural deformations in the host to accommodate ...

Linker‐Locking Strategy for the Rigidification of Flexible Metal–Organic Framework: Structural Stabilization and Controlled ESIPT for H2O/D2O Sensing

Advanced Science, EarlyView.
A linker‐locking strategy rigidifies the flexible metal–organic framework (MOF) MIL‐53‐(OH)2 via the cooperative encapsulation of ligands and structural water. This network significantly enhances the framework's aqueous stability. Crucially, rigidification suppresses enol emission to yield a single keto tautomer state with an extended lifetime ...

Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

Advanced Science, EarlyView.
A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Supramolecular Chiral Assemblies from Benzoselenadiazole‐Alanine‐Acylhydrazone Conjugates Enable Cardioprotection

Advanced Science, EarlyView.
The C3‐symmetric conjugate TASe, which integrates benzoselenadiazole, alanine, and acylhydrazone modules, self‐assembles into a chalcogen‐/hydrogen‐bonded porous framework in the solid state and uniform chiral nanospheres in aqueous media. These assemblies protect cardiomyocytes from doxorubicin‐induced oxidative injury by scavenging intracellular ...

Cucurbit[n]uril : a new molecule in host-guest chemistry

, 2006
Cucurbit[n]uril, CB[n], is made from the condensation of glycoluril and formaldehyde in concentrated acid solutions (Fig. 1). It was first made in 1905 as the six-subunit macrocycle CB[6] but its structure was not determined until 1981.[1] Over the last ...

Non‐Covalent Reversibly Photoconvertible Fluorescent Tags for Wash‐Free Protein Labeling

Advanced Science, EarlyView.
FAST proteins combined with one or two fluorogens undergo reversible fluorescence switching or photoconversion through photoisomerization. At low fluorogen concentration and high light intensity, they act as negative or positive photoswitchers and photoconvertible tags, which are promising for discriminating FAST variants.
