Integrated Multiband Smart Windows From UV to LWIR Based on Molecularly Engineered Thermochromic Hydrogels

Advanced Functional Materials, EarlyView.
A multiband smart window integrating a thermochromic poly (EEEA‐co‐NIPAM) hydrogel with functional layers, enabling dynamic VIS‐NIR solar modulation alongside UV shielding and low LWIR emissivity. The polymer network forms hydrogen‐bonding interactions, promoting chain collapse above a reduced lower critical solution temperature, and accelerating the ...

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

Advanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.
