Strain‐Activated Photo‐Dehalogenation Unlocks Low‐Energy One and Two‐Photon 3D Microfabrication

Advanced Functional Materials, EarlyView.
5,14‐NMI‐Cz acts, conversely to its 7,10‐NMI‐Cz(7,10‐'dibromo‐2‐(2,6‐diisopropylphenyl)‐1H‐benzo[lmn]carbazolo[9,1‐bc][2,8]phenanthroline‐1,3(2H)‐dione) counterpart, as modular photoinitiator with panchromatic photoactivity, featuring a weak C–Br bond from geometric strain for efficient Type I & II initiation. These studies demonstrate applicability of

Catalysis of a Bis-Caffeine Palladium(II) NHC-Pincer Complex

Inorganics, 2023
A tridentate bis-NHC Pd complex, based on caffeine, was studied for its catalytic activity. This complex displayed a high catalytic activity in the Suzuki–Miyaura and Mizoroki–Heck cross-coupling reactions of aryl halides.

Design of Efficient and Mechanically Robust Anion Exchange Membrane for Water Electrolysis Achieved by Chemically Crosslinked Elastomers using Polyfluorene‐Based Conjugated Polymers

Advanced Functional Materials, EarlyView.
High‐performance SEBS‐PFB AEM is developed by crosslinking SEBS‐amine with polyfluorene‐based crosslinker containing benzene spacer. With the superior electrochemical and mechanical properties, SEBS‐PFB enabled an AEMWE single cell to achieve a high current density of 14.0 A cm−2 at 2.0 V and 80 °C in 1 m KOH, using a PtRu/C cathode and Ni2Fe anode ...

Assembly of (hetero)aryl sulfilimines via copper-catalyzed enantioselective S-arylation of sulfenamides with (hetero)aryl Iodides

Nature Communications
The (hetero)aryl sulfoximines are important structures for developing bioactive molecules, whose synthesis relies on oxidation of (hetero)aryl sulfilimines. However, asymmetric approaches for assembling (hetero)aryl sulfilimines are still rare.
