Angewandte Chemie, EarlyView.A bifunctional metal‐organic framework (MOF) catalyst with dual active sites is developed for enabling NH2OH electrosynthesis via NitRR with both high selectivity and activity. ABSTRACT Electrocatalytic nitrate reduction reaction (NitRR) offers a promising route for hydroxylamine (NH2OH) synthesis under ambient conditions.

Metal phthalocyanine intermediates for the preparation of polymers [PDF]
, 1985 Metal 4, 4', 4"",-tetracarboxylic phthalocyanines (MPTC) are prepared by reaction of trimellitic anhydride, a salt or hydroxide of the desired metal (or the metal in powdered form), urea and a catalyst.

Advanced Science, EarlyView.We report a general strategy for meta‐selective C–H arylation using aryl iodides and a Pd(II)/Pd(IV) catalytic system guided by a removable directing group. DFT and experimental studies reveal that counter anion tuning (acetate to trifluoroacetate) significantly enhances selectivity.

Atroposelective Suzuki–Miyaura Coupling to Form 2‐Amino‐2′‐Hydroxybiphenyls Enabled by sRuPhos
Angewandte Chemie, EarlyView.We report a new chiral phosphine ligand, sRuPhos, which permits the highly enantioselective Suzuki–Miyaura coupling of ortho‐aniline and ortho‐phenol building blocks. This results in 2‐amino‐2′‐hydroxybiphenyls with very high enantiomeric excesses, products that will have application in pharmaceutical synthesis and ligand design for catalysis ...

Synthesis and optoelectronic properties of new ethynylated pyrazine derivatives [PDF]
, 2003 Several diaryleneethynylpyrazine derivatives, in which the pyrazine unit is electron-deficient, have been synthesised using Sonogashira palladium-catalysed cross-coupling reactions.

Observation of Edge‐Confined Acoustic Hyperbolic Polaritons in van der Waals Materials
Advanced Science, EarlyView.This work demonstrates a new type of light wave—edge‐confined acoustic hyperbolic polaritons—in hexagonal boron nitride on gold. These waves travel along crystal edges with nanoscale confinement and strongly interact with molecular vibrations, enabling highly sensitive detection of tiny molecular layers.

Angewandte Chemie, EarlyView.Multiphase systems, including ones with liquid‐liquid phase boundaries, are the home to many curious chemistries including reaction acceleration and spontaneous formation of reactive species. Here we show the liquid‐liquid interface causes electrochemiluminescence and afterglow chemiluminescence lifetime to be enhanced by 220,000% in‐time, far beyond ...

Advanced Science, EarlyView.A late‐stage diversification strategy for the benchmark MR‐TADF emitter ω‐DABNA enables precise electronic structure control via chlorine‐activated functionalization. The resulting derivatives achieve tunable emission from 523 to 533 nm with record‐high EQE1000 up to 34.0% and excellent color purity (CIEy = 0.70–0.73), establishing a versatile platform
