Advanced Science, EarlyView.The electrolyte engineering of introducing tetrakis(4‐N, N‐dimethylaminophenyl)porphyrin (TDMAP) is designed to modulate Li+ solvation structure and solid electrolyte interphase, where the interaction with PF₆− anions is altered (Li+–NMe2–PF₆−). Consequently, the cells with optimal additive concentration achieve high Coulombic efficiency (∼99%), and ...

Catalytic Functionalization of Unactivated π‐Bonds Enabled by Bidentate Directing Auxiliaries
Angewandte Chemie, EarlyView.This review explores how bidentate directing auxiliaries have advanced transition‐metal catalysis for unactivated alkene/alkyne functionalization. By leveraging chelated intermediates, bidentate directing auxiliaries enable precise hydrofunctionalization, difunctionalization, and C─H activation of π‐bonds with unique selectivity and reactivity.

Advanced Science, EarlyView.We report photostable, photoluminescent deep eutectic solvents (DESs) powered by in situ‐formed zero‐dimensional (0D) halometallates. Stabilized by microenvironment‐controlling hydrogen bond acceptor (HBA) and donor (HBD) networks, these DESs exhibit vibrant, metal ion‐tunable emission (PLQY = 60.2%).

Ultra‐Thin and Highly Insulating Aromatic Monolayers by N‐Heterocyclic Carbenes
Angewandte Chemie, EarlyView.By using N‐heterocyclic carbenes extremally insulating and at the same time as thin as 0.3 nm molecular films are formed. The charge transport calculations indicate absence of destructive quantum interference effect which was so far the only way to suppress conductivity in aromatic molecules.

Multicomponent Syntheses of glycoside-decorated N-heterocyclic pharmacophores
, 2006 We report in this communication on the synthesis of carbohydrate decorated N-heterocycles, namely dihydropyrimidin-2-ones, dihydropyridines, and azetidin-2-ones, via multicomponent Biginelli, Hantzsch, and Staudinger reactions ...

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

Pyridine C─N Transposition via Cycloaddition–Cycloreversion
Angewandte Chemie, EarlyView.Transposition of pyridine nitrogen from the 4‐ to the 3‐position is described using two open and shut sequences: a nucleophile addition ring‐open ring‐closure, followed by a nitrile Diels–Alder cycloaddition cycloreversion. The nitrogen swap is particularly effective for tertiary alkyl substituents, transforming easily accessible para‐alkylated ...
