Novel base-catalyzed acylation of benzene diols with vinyl acetate: A Hirshfeld surface study

open access: yes
The present work describes the facile, fast, and economic base-catalyzed acylation of benzene diols with vinyl acetate. The Hirshfeld surface analysis of benzene-1,4-diol O,Oʹ-diacetate is also described.

Electrochemical Fluorination of Partially Fluorinated Dialkylethers. Synthesis of Sevoflurane Derivatives (CF3)2CHOCHF2, (CF3)2CHOCF3, and (CF3)2CFOCF3

open access: yesChemistry – A European Journal, EarlyView.
Electrochemical fluorination (ECF, Simons process) is a valuable method for the fluorination of partially fluorinated dialkyl ethers, providing an inexpensive, scalable, and safe access to partially fluorinated ethers with a higher fluorine content and the perfluorinated analogues that are hardly accessible using other fluorination techniques ...

Proximal Steric Shielding Unlocks High Solid‐State Luminescence in Quinoxaline‐Fused Pyrene Heteroacenes

open access: yesChemistry – A European Journal, EarlyView.
Proximal steric tuning of quinoxaline‐fused pyrene heteroacenes enables soluble derivatives that exhibit solid‐state photoluminescence quantum yields (PLQYs) up to 82%, surpassing previous benchmarks. This work reveals key structure–property relationships for next‐generation, processable organic emitters in advanced optoelectronic applications ...

Xanthene‐Based FLPs Featuring Perchloroarylborane Substitutents: Interplay of Noncovalent Aggregation and Dihydrogen Activation

open access: yesChemistry – A European Journal, EarlyView.
Frustrated Lewis Pairs featuring perchloroarylborane Lewis acid groups are found to display unprecedented H2 uptake as a function of temperature, resulting from the thermodynamic balance between H─H cleavage and noncovalent intermolecular aggregation.

Designing Threefold π‐Surfaces Through Peripheral Halogenation to Shape Multidirectional Molecular Packing

open access: yesChemistry – A European Journal, EarlyView.
The complete series of hexahalogenated triptycene‐tribenzoquinones, comprising newly synthesized fluoro‐, bromo‐, and iodo‐substituted derivatives together with the previously reported chloro analogue, enables systematic comparison of their molecular properties and intermolecular interactions in relation to their crystal packing modes.

Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

open access: yesEcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...
