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 ...

Large Electrogyration Effect in Ferroaxial NiTiO3 at Near Infrared Wavelengths
Advanced Optical Materials, EarlyView.A large electrogyration effect (electric field‐induced optical rotation) is observed in a ferroaxial crystal NiTiO3 at near infrared wavelengths. The Ni2+ d‐d transitions, featuring strong magnetic dipole character, play an important role in producing the pronounced effect.

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 ...

Advanced Optical Materials, EarlyView.This study investigates the impact of solvent systems on the uniformity of the ZnO electron transport layer (ETL) in inkjet‐printed electroluminescent quantum dot (EL‐QD) devices. The mixed‐solvent approach effectively suppresses the coffee‐ring effect, enhances charge injection, and improves luminance, ultimately contributing to the optimization of EL‐
