Artemisia selengensis Leaves, a Vegetable Waste: LC‐MS‐Based Chemical Profiling, Ultrasound‐Assisted DES Extraction, and Xanthine Oxidase Inhibitory Activity

open access: yeseFood, Volume 7, Issue 1, February 2026.
This study focused on Artemisia selengensis leaves (ASL), a discarded agricultural waste. 72 compounds were identified by UPLC‐Q‐TOF‐MS. “Green” extraction with DES was optimized, and ASL's XO—inhibition was explored, presenting new ways for waste utilization. ABSTRACT Artemisia selengensis is a medicinal and edible plant, whose tender stems are widely

Probing a Reactive Alkyne Center Aligned via a Triphenylmethane Tripod on Au(111) for Electric Field‐Induced Chemistry by STM and TERS

open access: yesSmall, Volume 22, Issue 7, 2 February 2026.
Electric‐field‐induced chemistry at solid/vacuum interfaces offers precise control over chemical reactions. In this study, a triphenylmethane‐based tripod with a terminal alkyne is anchored upright on a gold surface. Advanced scanning tunneling microscopy and tip‐enhanced Raman scattering confirm the alignment and stability of the reactive center ...

Thiophene Derivatives as Versatile Precursors for (Hetero)Arene and Natural Product Synthesis

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Hidden but Powerful: Thiophenes and their saturated analogues have been demonstrated to be versatile C4‐building blocks that can be rapidly applied to natural product synthesis and the construction of functionalized (hetero)arenes. This minireview aims to provide a concise overview of the strategies and implementations of these sulfur‐containing ...

Taming of Low‐Valent Arsenic Compounds and Transfer of Nascent As2 Facilitated by a Frustrated Lewis Pair

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
A series of frustrated Lewis pair (FLP) stabilized arsenic compounds with formal oxidation numbers at As of +1, 0, and −1 are presented. A stable FLP‐chelated complex of As2 was prepared which undergoes the light‐induced release of nascent diarsenic, As2nasc, which reveals clean triple‐bond type reactivity with dienes and metal‐metal bonds under mild ...

Hexabenzocoronene–Benzimidazole Hybrid Architectures and Faraday Rotation of the First Hexabenzocoronene–Phthalocyanine

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
The synthesis of four hexabenzocoronene (HBC) benzimidazole hybrid molecules is shown, culminating in tetra‐HBC‐Ni‐phthalocyanine (Pc). Its application as a Faraday rotator reveals a remarkable Verdet constant. The compounds are fully characterized and their optoelectronic properties investigated by electrochemistry, UV–vis, and fluorescence ...
