Potassium‐Ligand Cooperation Facilitated Chemical Bond Activation and Catalytic Hydrogenation

Angewandte Chemie, EarlyView.
A new strategy for alkali metal‐mediated catalysis based on metal–ligand cooperation (MLC) is presented. Potassium pincer complexes exhibit remarkable reactivity toward a range of molecules via an unprecedented potassium–ligand cooperative mechanism. This reactivity enables potassium‐catalyzed hydrogenation, providing efficient reduction of ketones and

Ultrastable Self‐Cross‐linkable Electro‐Optic Materials Based on a Bisanthracene Scaffold

Advanced Electronic Materials, EarlyView.
A novel bisanthracene‐based self‐cross‐linkable electro‐optic chromophore (TD2) is developed. TD2 exhibits a high r33 of 141 pm/V and a cross‐linked Tg up to 195 °C, retaining 99.75% of its initial EO response after 500 h at 85 °C, showing record‐high thermal stability for single‐molecule self‐cross‐linking EO materials.

Interaction Hierarchy and Polymorphic Structure–Property Dynamics in Luminescent Molecular Crystals

Angewandte Chemie, EarlyView.
Competing homotypic and heterotypic intermolecular interactions give rise to polymorphic structure–property dynamics in luminescent molecular crystals. Thermal and mechanical stimuli induce distinct phase‐transition pathways accompanied by pronounced photoluminescence changes.

The Chemistry and Biology of Benz[a]anthracenes

, 1988
First published in 1988, this volume surveys the chemical synthesis and biological activity of the benz[a]anthracenes. These compounds occur in smoke and mineral oils and a few have been shown to be potent carcinogens. This volume was the first to review,

Aromaticity and conformational deformability of some environmental pollutants - methylated anthracenes

, 2014
There is little information on methylated anthracenes which are constituents of diesel fuel. In this paper, a theoretical investigation of some molecular properties of methyl-anthracenes (MAs), 1-MA and 2-MA, and all dimethylanthracene isomers (DMAs), 1 ...

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...
