Structural Relaxation Modulated Phonon‐Assisted Energy Transfer Scintillator for Simultaneous X‐Ray Imaging and Thermal Signals Visualization

ABSTRACT Abnormal overheating often leads to malfunctions in electronic components during operation. Although traditional scintillators have shown great potential in object imaging, they are often unable to capture thermal signals. In this work, a series of Tb 3+ /Eu 3+ co‐doped...

Diffusion‐Driven Macromolecular Self‐Organization Enables Conformal Perovskite/Silicon Tandems

ABSTRACT Industrial deployment of perovskite/silicon tandem solar cells is limited by the difficulty of forming thick, defect‐controlled wide‐bandgap (WBG) perovskite layers that conformally coat micron‐textured silicon while retaining interfacial passivation. Here, we introduce...

Ultrathin 2D Multivariate Hydrogen‐Bonded Organic Framework Nanosheets for Fluorescent DNA Sensing

The multivariate strategy is generally incompatible with densely packed structures, as this approach typically requires porous frameworks to manage the steric demands of incorporated functional groups. Without sufficient free volume, the frameworks are prone to structural transfo...

Solvent‐Induced Structural Modulation in Nanoscale Covalent Organic Frameworks Enables High‐Performance NO 2 Sensing

ABSTRACT Covalent organic frameworks (COFs) offer exceptional structural and functional tunability, enabling performance optimization in separation, catalysis, and sensing applications. Here, we report a solvent‐induced strategy for inducing structural disorder in porphyrin‐based...

Designing Novel Solar‐Blind Ultraviolet Nonlinear Optical Crystals Based on Local Proton Distribution Complementary Effect

ABSTRACT Dipolar π‐conjugated groups with large polarizability anisotropy and hyperpolarizability are generally regarded as important nonlinear optical (NLO) active building units. However, their strong dipole‐dipole interactions remain a key challenge in designing non‐centrosymm...

Cation‐Engineered Narrow‐Band Green Emitting Phosphor Toward High‐Performance Laser‐Driven Displays

ABSTRACT Wide color gamut and high brightness are critical performance metrics for advanced displays like projectors. Combining narrow‐band green and red color converters with a blue laser‐driven light source is one of the most effective solutions to achieve these goals. In this...

IntramolecularHeterojunctions for Highly SensitiveRoom-Temperature NO2 Sensing

Abstract Heterojunction materials achieve efficient charge transfer and carrier separation through built-in- electric fields at the interfaces, thereby substantially enhancing the sensitivity and selectivity of gas sensors. However, traditional particle-contact heterojunctions su...

Photo/Copper-CatalyzedOxidative Direct Diphosphorothiolationof Indolin-2-ones with P(O)SH Compounds

Abstract A visible-light-promoted cross-dehydrogenative coupling (CDC) of indolin-2-ones with S-hydrogen phosphorothioates via 4H elimination has been developed, providing 3,3-diphosphorothiolated oxindoles in good yields with broad functional group tolerance. The protocol was al...

Reversed Quantum‐Well Engineering Unlocks Large Ultraviolet Chiral Nonlinear Optical Response in a Water‐Resistant 2D Hybrid Fluorozirconate

ABSTRACT Two‐dimensional (2D) chiral organic–inorganic hybrid metal halides (OIHMHs) are promising for chiroptical applications. However, conventional Ge/Sn/Pb‐based systems remain limited by narrow bandgaps and poor moisture stability. In this work, we report the first 2D chiral...
