Chiral Sensing of Amino Acids under Visible Light via Hydroxypropyl Cellulose Gels

Advanced Optical Materials, EarlyView.
Hydroxypropyl cellulose gels enable visible‐light‐based chiral detection of amino acid enantiomers. This study showcases their structural color properties for distinguishing phenylalanine and alanine enantiomers. The gels exhibit pH‐responsive color changes, high sensitivity at low concentrations (0.2 wt.%), and long‐term stability, offering ...

Monolithic Integration of GaN Thin Film and GaN Nanorods Pixels: Facile Growth of InGaN/GaN Quantum Wells for the Realization of Full Color Micro‐LED Display

Advanced Optical Materials, EarlyView.
This work implements an advanced lithographic technique to fabricate a template to exploit the indium incorporation efficiency of crystallographic orientations of GaN and demonstrates green and blue self‐emissive µLED pixels through an integration of MOCVD growth technique, device fabrication and phosphor conversion for the realization of full‐color ...

Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

Advanced Optical Materials, EarlyView.
Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...

Simultaneous Emission Spectral Narrowing and Spin‐Flip Acceleration in Multi‐Resonance Organoboron Emitters via Sequential Indolo‐Fusion π‐Extension

Advanced Optical Materials, EarlyView.
Sequential indolo‐fusion π‐extension as a rational design strategy to further narrow the emission bandwidth of multi‐resonance thermally activated delayed fluorescence is introduced. By fusing one or two additional indole moieties to the periphery of Cz‐B, gradual spectra narrowing and accelerated triplet–singlet exciton spin conversion are ...
