Discovery, Herbicidal Activity and Biosynthesis of a Novel Natural Tetramic Acid from Alternaria Species

open access: yesAdvanced Science, EarlyView.
The biosynthetic mechanism of novel natural tetramic acid S‐TeA in Alternaria alternata is elucidated. Threonine acts as a precursor for 2‐amino‐3‐methylhexanoic acid (AMHA) synthesis via eight key enzymes from the branched‐chain amino acid biosynthetic pathway in the mitochondrion, wherein three unique enzymes (IPMS, IPMDH, and ISMD) play critical ...

Pyridine‐Fused Bis(azacorrole)s: Easily Accessible NIR III Absorbing Cation Radicals and Biradicaloids of Antiaromatic Ground State

open access: yesAdvanced Science, EarlyView.
A series of pyridine‐fused hetero‐ and homodimers containing azacorrole moiety is obtained. The spectral, redox, and magnetic properties of the bis(azacorrole)s reflect an electron‐donating character of these systems and interaction between the subunits which depends on the substitution pattern.

Tuning Aggregation in Liquid‐Crystalline Squaraine Chromophores

open access: yesAdvanced Science, EarlyView.
A novel squaraine dye (SQ) forming columnar liquid crystal (LC) phase is synthesized, whose aggregate state can be tuned without disturbing the columnar structures. The liquid crystallization not only offers a rich spectrum and tuning method of optical property but also a novel path for the prescriptive functionalization of LC SQ materials.

Residual Stresses and Micro‐voids Propel Metal Diffusion for Filament‐Based Memristors

open access: yesAdvanced Science, EarlyView.
Introducing non‐reactive nitrogen during silver sputtering enables low‐voltage (<60 mV) switching in memristors via nano‐void formation and residual stresses in the gigapascal range. This promotes sub‐micron filamentation and neuromorphic behaviors, including multi‐peak synaptic responses.
