Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

Advanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Solvent‐Induced Octahedral Self‐Assembly of Prussian Blue and Its Applications in Sodium‐Ion Capacitors

Advanced Functional Materials, EarlyView.
This study investigates the stepwise assembly process of octahedral Prussian Blue (PB) particles in glycerol. Initially, smaller cubic PB nanoparticles form and interact in the solvent. Over time, these particles undergo dissolution and reassembly, leading to the formation of well‐defined octahedral structures with minimized surface energy.
