Disrupting J‐Aggregation in Triazatruxene Dimers to Develop Responsive Luminescent Inks for Anti‐Counterfeiting Applications

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...

Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.
