Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation

Angewandte Chemie, EarlyView.
Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...

Temperature‐Responsive Near‐Infrared Emission Enabled by Reversible π‐Umpolung with an Alkenyl‐Strapped Diarylboryl Unit

Angewandte Chemie, EarlyView.
Coordination of a Lewis base switches an electron‐accepting tricoordinate boron center into an electron‐donating tetracoordinate one. An alkenyl‐strapped diphenylthienylboryl π‐system undergoes phosphine‐induced reversible π‐umpolung, where transformation from an acceptor–acceptor–acceptor framework to a donor–acceptor–donor system gives rise to ...

Haptic In‐Sensor Computing Device Based on CNT/PDMS Nanocomposite Physical Reservoir

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Using a porous carbon nanotube‐polydimethylsiloxane nanocomposite, a sensor array integrated with a physical reservoir computing paradigm capable of in‐sensor computing is demonstrated. The device is able to classify between nine objects with an accuracy above 80%, opening the possibility for low‐power sensing/computing for future robotics.

Sustainable Ammonia Electrosynthesis Coupled With Glycerol Valorization via an Adaptive Tri‐Component Catalyst

Angewandte Chemie International Edition, EarlyView.
A Cu‐Ni‐W tri‐component catalyst enables efficient nitrate‐to‐ammonia conversion under pulsed electrolysis. Combined experimental and theoretical studies attribute its performance to component synergism and regulated intermediates. Its facile adaptation for glycerol valorization to formic acid underscores a versatile system design concept, advancing ...
