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

ABSTRACT “Dark photocatalysis” decouples electron storage from photoconversion, offering a promising route to buffer solar intermittency, however requiring precise control of light‐matter interactions. Metal–organic frameworks (MOFs) provide a platform to tailor these interaction...

Lithium Makes the Difference─Evolution of Lithium Vacancy Disorder during Temperature-Induced Phase Transitions of the Li-Ion Conductor Li4SnS4

Abstract Sulfide-based lithium-ion solid electrolytes are promising candidates for solid-state batteries due to their high ionic conductivities, although they typically exhibit high moisture sensitivity. Li4SnS4 has recently attracted scientific interest because it exhibits highe...

From Surface Buffering to Bulk Ion Exchange: Mapping the Acid Response of Potassium Poly(Heptazine Imide) (K-PHI)

Abstract Potassium poly(heptazine imide) (K-PHI) is a promising material for photocatalysis and energy storage, yet its application in aqueous media is limited by protonation. Cation exchange to protonated poly(heptazine imide) (H-PHI) causes structural and optoelectronic changes...

Direct Light Storage with Controlled Dark Release in a Bipyridine-Based Covalent Triazine Framework

Abstract Utilizing bifunctional materials capable of direct light-to-charge storage offers an attractive strategy to overcome solar intermittency and enable reliable power supply under dark conditions. Reported bifunctional materials are predominantly based on metal oxides and me...
