Intermolecular Aggregation‐Induced Delayed Fluorescence Scintillators for Ultrahigh‐Resolution X‐Ray Imaging

Advanced Science, EarlyView.
An intermolecular AIDF strategy enables an organic X‐ray scintillator (OXST) that resists concentration quenching and efficiently utilizes singlet and triplet excitons. The AIDF emitter, embedded in a polysulfone matrix, yields bright, flexible, and transparent scintillation screens with ultralow detection limits and high spatial resolution, offering a

Ultrathin Quasi‐2D Perovskite‐Organic Segregated‐Structure Coupling for High‐Performance Narrowband Photomultiplication Detectors

Advanced Science, EarlyView.
Quasi‐2D perovskite‐organic segregated‐structure coupling enables low‐power narrowband photomultiplication photodetectors with 110 nm perovskite layer. The optimal device achieves 1200% EQE and 1.82 × 1011 Jones D* at 3 V, offering a new strategy for miniaturized high‐selectivity optoelectronic sensing.

Helicalization of Covalent Organic Framework Nanofibers with Amplified Spin Polarizability for Boosting Photocatalytic Hydrogen Evolution

Advanced Science, EarlyView.
A non‐covalent chirality‐induced strategy via chiral solvents is presented to synthesize helical 2D COF nanofibers with high crystallinity, high chirality, and high spin polarization. The helical structure enhances the concentration of photogenerated charges, suppresses exciton recombination, and extends carrier lifetimes, thereby significantly ...

One‐Step, High‐Removal‐Rate and Low‐Damage Chemical Mechanical Polishing of InP Enabled by Hydrolysis Activated PF6− with In Situ Fluoride Passivation

Advanced Science, EarlyView.
In this work, we propose a CMP method for InP using NH4PF₆, which hydrolyzes under In3+ catalysis to form reactive species. These convert InP into low‐binding‐energy fluorides, facilitating removal and dissolution. The process delivers high material removal rates, smooth surfaces, and fluorine passivation that lowers defect density and improves ...

Dual‐Mode Type I/II Photosensitization of a Stable Mesoporous Hydrogen‐Bonded Organic Framework for Antibacterial Therapy

Advanced Science, EarlyView.
A π‐conjugated donor–acceptor PDI monomer undergoes hydrogen‐bonded self‐assembly to form a robust mesoporous framework. The ordered molecular arrangement promotes efficient intersystem crossing and charge separation, leading to simultaneous Type I and Type II reactive oxygen species generation with a high singlet oxygen quantum yield.
