Molecular Nanoarchitectonic Sensing Layer for Analysis of Volatile Fatty Acids in Bioreactor Headspaces Using a Nanomechanical Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
A porous crystalline sensing layer has been developed in conjunction with a nanomechanical sensor for the sensitive detection of volatile fatty acids (VFAs) in admixture at high relative humidity. The sensitive, selective sensor based on supramolecular design improves the economic viability of anaerobic digesters toward a carbon neutral society ...

Polymer Dots Exhibiting Multi‐Resonant Thermally Activated Delayed Fluorescence for Cellular Imaging

open access: yesAdvanced Optical Materials, EarlyView.
By copolymerizing with a host material, a multiple resonance thermally activated delayed fluorescent (MR‐TADF) emitter quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) is successfully assembled into water‐dispersible polymer dots (Pdots). Photophysical measurements and multichannel fluorescence imaging studies show that the narrowband emission from the MR ...

Oligomerization‐Induced Supramolecular Glass with Superior Processability and Optical Functions

open access: yesAdvanced Optical Materials, EarlyView.
Oligomerization‐induced supramolecular glass (BGG) is formed via a catalyst‐free melt‐quenching strategy from benzoguanamine. The in situ formation of diverse oligomers suppresses crystallization, enabling glass formation. BGG exhibits a high Tg (100.1 °C), polymer‐like modulus, and bright aggregation‐induced emission, and is readily processed into ...

Synthesis of Spirolactones from Carbonyls via Carboborylation of N‐Sulfonylhydrazones with Alkoxycarbonylalkylboronic Acids

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Spirolactones are readily prepared from carbonyls via their N‐tosylhydrazones. The reaction involves carboborylation with ethoxycarbonyl‐substituted boronic acids, followed by oxidation and lactonization. Thermal or photochemical protocols enable versatility.

Asymmetric Strategies for the Synthesis of Enantiopure α‐/β‐/γ‐Thio‐Carboxylic Acids Bearing a Stereocentre at CS Bond

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Enantioenriched α‐/β‐/γ‐thiocarboxylic acids featuring C–S chirality are valuable targets in organic synthesis. This review outlines recent progress in their asymmetric synthesis, including chiral pool approaches, metal‐ /organo‐catalysis, and emerging biocatalytic strategies. Enantiomerically pure α‐/β‐/γ‐thiocarboxylic acids bearing a stereocentre at
