Stimuli‐Responsive Low‐Frequency Terahertz Absorption ON‐OFF Switchability in Spin‐Crossover Material

Advanced Materials, EarlyView.
A switchable Fe(II)–Hg(II) coordination polymer exhibits reversible ON‐OFF terahertz (THz) absorption through temperature‐ and light‐induced spin‐crossover. The material shows strong, tunable THz responses linked to phonon modes around Fe(II) centers, supported by spectroscopic measurements and calculations.

Polycondensation as a Universal Method for Preparing High‐Density Single‐Atom Catalyst Libraries

Advanced Materials, EarlyView.
This paper presents a universal bottom‐up polycondensation strategy for synthesizing high‐density single‐atom catalysts (HD‐SACs) with metal loadings up to 27.5 wt%. Using various metal monomers with 1,10‐phenanthroline‐5,6‐dione ligands, it generates atomically dispersed mono‐ and bimetallic HD‐SACs.

Multimaterial 3D Printing in Activating Bath Enables In Situ Polymerization of Thermosets with Intricate Geometries and Diverse Elastic Behaviors

Advanced Materials, EarlyView.
A new embedded 3D printing (EMB3D) strategy enables in situ polymerization of DCPD/COD‐based inks within a fugitive reactive matrix where the activator in the matrix cures the printed filament. Cured ink properties are tunable through DCPD‐COD comonomer ratios, yielding materials from stiff thermosets to soft elastomers.

Ion Valency as a Molecular Switch for Salt‐Resistant Underwater Adhesion

Advanced Materials, EarlyView.
Monovalent K+ ions weaken adhesion by forming K+‐π complexes with weak bridging capacity. In contrast, multivalent cations like Y3+ enhance adhesion by forming stable π‐cation‐π bridging networks, which are resistant to salt and capable of compensating for the loss of native π–π and NH3+‐π interactions.

Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

Advanced Materials, EarlyView.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...
