Advanced Materials, EarlyView.Structural water is harnessed as an active co‐monomer to drive supramolecular polymerization in bulk water. Zinc(II) Salphen complexes confine water molecules to form hollow, metal–organic nanofibers that assemble into adaptive hydrogels with thermoresponsive mechanics and selective chiral recognition.

Ligand‐Mediated Surface Carrier Modulation in Perovskite Nanocrystals for Charge‐Symmetric LEDs
Advanced Materials, EarlyView.A hydrolysis‐assisted ligand exchange strategy enables surface carrier modulation of perovskite nanocrystals using a multifunctional π‐conjugated ligand. This molecular surface design achieves charge balance and recombination‐zone symmetry in light‐emitting diodes (LEDs), which leads to high‐efficiency perovskite LEDs and establishes a general platform
