Charge Storage and Dark Photocatalysis in Multivariate Ti‐Based Metal‐Organic Frameworks

Advanced Materials, EarlyView.
The mixed‐linker series of the titanium‐based metal–organic framework COK‐47 enables systematic tuning of photoresponsiveness and (dark) photocatalytic activity, deepening our understanding of structure‐property‐function relationships. Tailored metal‐to‐ligand charge transfer between the secondary building units (metal‐oxo layers and organic linkers ...

Coordination Bridges in Confined‐Water Domains Enable Partially Desolvated Zn2+ Transport in Aqueous Zinc‐Ion Batteries

Advanced Materials, EarlyView.
A multifunctional polymer layer with amide and imidazolium groups simultaneously suppresses dendrite growth and hydrogen evolution in Zn‐ion batteries. By providing Zn2+ binding sites and forming a confined‐water domain that acts as a coordination bridge, it boosts single‐ion conductivity and stability, enabling 4000 stable cycles in Zn‐I2 full cells ...
