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

Chemistry – 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.

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

EcoEnergy, 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 ...
