Stimuli‐Responsive Hierarchical Structuring Controls Survival and Programs Hydrogelation of Supramolecular Metallofibers

open access: yesAdvanced Materials, EarlyView.
Aqueous Zn(II) Salphen metallofibers decorated with PNIPAM undergo reversible, multi‐stimuli‐responsive hierarchical bundling. This higher‐order structuring kinetically stabilizes the otherwise fragile assemblies against dilution, acidic hydrolysis, and transmetallation, enables selective sorting of responsive fibers, and programs hydrogelation at ...

Rotational Isomers of Diphenhydramine

open access: yesYAKUGAKU ZASSHI, 2018
 Diphenhydramine (DP), an antihistaminic agent, may become colored and daker or more fluorescent during storage. Herein, we spectroscopically examined the causes of this phenomenon under various DP storage conditions and durations. The infrared vibration-rotation spectrum shows multiple Gauche (G)-type conformers with different intramolecular n→π ...

True Closed‐Loop Recyclable Hydrogels Enabled by Imine Boronic Ester Crosslinking

open access: yesAdvanced Materials, EarlyView.
Subtle molecular differences in imine boronic ester crosslinkers profoundly influence hydrogel properties. 2‐formylphenylboronic acid crosslinkers form previously undisclosed 3‐amino‐benzoxaborole heterocycles, enhancing elasticity despite lower crosslinking density compared to their 4‐formylphenylboronic acid counterparts.

New Trend of Amperometric Gas Sensors Using Atomic Gold-Decorated Platinum/Polyaniline Composites

open access: yesChemosensors
The Amperometric Gas Sensor (AGS) uses an electrode as the transducer element which converts its signal into a current from the electrochemical reaction of analytes taking place at the electrode surface.

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

open access: yesAdvanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.
