Achieving Dynamic Circularly Polarized Luminescence with 2D Hydrogen‐Bonded Organic Frameworks

open access: yesAdvanced Science, EarlyView.
Efficient chirality transfer and circularly polarized luminescence (CPL) are realized by incorporating chiral carvone molecules into the 1D channels of luminescent hydrogen‐bonded organic frameworks (HOFs). These materials display dynamic CPLs with varied emission colors via a guest desorption‐triggered interlayer contraction mechanism.

Transition Metal Slab Gliding: One Key Process for Activating Anionic Redox Reaction in P2‐Type Transition Metal Oxide Cathodes

open access: yesAdvanced Science, EarlyView.
Transition metal (TM) slab gliding is a key process for activating anionic redox reaction in P‐type layered oxide materials. Disordered TM layer weakens interlayer interactions and facilitates TM slab gliding. The resulting O‐type layer promotes reversible TM migration, provides the necessary Na–O–□TM configuration, and activates anionic redox reaction.

Dynamic Molecular Cocrystals with Alkyl Chain Dependent Thermosalient Phase Transitions

open access: yesAdvanced Science, EarlyView.
A series of cocrystals containing 5‐fluorocytosine and fatty acids with varying alkyl chain lengths are synthesized, demonstrating a systematic modulation of thermosalient phase transition temperatures across a broad range (≈100 K). This study reveals a linear correlation between interlayer hydrophobic interactions and transition temperatures, offering
