Reenvisioning the De Mayo Reaction: A Boron‐Enabled Cycloaddition Approach

Angewandte Chemie, EarlyView.
An oxa‐boracycle conformational lock strategy enables photocatalytic [2+2] cycloaddition to afford densely substituted cyclobutylboronates. The conformational constraint suppresses triplet relaxation and promotes productive bimolecular reactivity.

Molecularly Engineered Wing‐Shaped Azobenzene Memristors for Logic‐in‐Memory and Edge Visual Intelligence

Advanced Science, EarlyView.
Rational engineering of terminal substituents in symmetric azobenzene‐based molecules enables precise control over conformationally coupled charge‐transfer processes. This design yields tunable nonvolatile resistive memory behaviors, ranging from write‐once‐read‐many‐times (WORM) to rewritable switching.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Guideline for High‐Performance Liquid Chromatography Detection of Anthocyanins

AgriFood: Journal of Agricultural Products for Food, EarlyView.
ABSTRACT Anthocyanins, as water‐soluble natural pigments widely present in plants, have various biological activities such as antioxidation and anti‐inflammatory, and are widely used in the fields of food, cosmetics, and medicine. However, because of the presence of unstable phenolic hydroxyl groups in their structure, they are prone to degradation due

Peroxide‐Assisted Solvate Engineering Enables Record‐High Birefringence in a Solar‐Blind Transparent Crystal

Angewandte Chemie, EarlyView.
H2O2‐directed solvate engineering reorganizes ∞[4HP] (4‐hydroxypyridine) chains from a crossed arrangement into a nearly parallel packing through strengthened hydrogen‐bonding interactions. The resulting peroxide‐containing crystal, 4HP·H2O2, exhibits a solar‐blind UV cutoff edge (278 nm) and giant birefringence (0.609 @ 546 nm). This work demonstrates

Generative and Experimental Validation of High Refractive Index Polymers via Domain Knowledge Approach with Small Data

Advanced Intelligent Discovery, EarlyView.
This research demonstrates that the combination of domain knowledge–based multiple regression, multi‐objective Bayesian optimization, and generative models is a suitable prediction tool for candidates of high refractive index polymers, even with the constraints in the model trained on limited data. The experimental validation can reproduce the proposed
