Machine Learning Driven Window Blinds Inspired Porous Carbon‐Based Flake for Ultra‐Broadband Electromagnetic Wave Absorption

Advanced Science, EarlyView.
Inspired by the regulation mechanism of window blinds, this study designs an electromagnetic wave‐absorbing metamaterial. By introducing the magneto‐electric coupling concept and integrating it with an artificial intelligence‐based data‐driven collaborative optimization strategy, the material optimizes impedance matching performance and enhances loss ...

Transformed Composite Sequences for Improved Qubit Addressing

, 2014
Selective laser addressing of a single atom or atomic ion qubit can be improved using narrowband composite pulse sequences. We describe a Lie-algebraic technique to generalize known narrowband sequences and introduce new sequences related by dilation and

Simultaneously Achieving Efficient Narrow‐Band Emission and Large Emission Dissymmetry Factor in an Achiral Hybrid Indium Chloride

Advanced Science, EarlyView.
This work demonstrates that efficient CPL, characterized by high PLQY, large glum, and narrow‐band emission, can be achieved simultaneously in a ligand‐modified hybrid indium chloride crystallizing in an achiral space group. ABSTRACT To achieve high contrast in three‐dimensional display, circularly polarized luminescence (CPL) materials should ...

Tellurophene‐Induced Triplet–Singlet Spin‐Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing

Angewandte Chemie, EarlyView.
Linking an auxiliary dibenzo[b,d]tellurophene unit markedly accelerates exciton spin conversion in multi‐resonance‐type thermally activated delayed fluorescence emitters. Owing to the heavy‐atom effect of tellurium, the corresponding OLEDs retain remarkably high external electroluminescence quantum efficiencies exceeding 25% even at an exceptionally ...

Record‐High Performance Hyperfluorescent OLEDs Achieved via Electronic Structure Control of Chlorine‐Diversified MR‐TADF Emitters

Advanced Science, EarlyView.
A late‐stage diversification strategy for the benchmark MR‐TADF emitter ω‐DABNA enables precise electronic structure control via chlorine‐activated functionalization. The resulting derivatives achieve tunable emission from 523 to 533 nm with record‐high EQE1000 up to 34.0% and excellent color purity (CIEy = 0.70–0.73), establishing a versatile platform

Broadband Achromatic Programmable Electromagnetic Camouflage via Fluidic‐Accessible Metasurface

Advanced Science, EarlyView.
A fluidic access metasurface enables dynamic, broadband electromagnetic illusions. By physically reconstructing conductive patterns with liquid metal, the metasurface achieves real‐time, pixel‐level control over phase dispersion. This allows for the programmable generation of arbitrary strong scattering point arrays, effectively deceiving high ...
