Bay‐functionalized [7]Helicene Bilayer Nanographenes

open access: yesAdvanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Highly Efficient Pure‐Blue Single‐Layer Organic Light‐Emitting Diodes Without High‐Triplet‐Energy Auxiliary Materials

open access: yesAdvanced Optical Materials, EarlyView.
Blue organic light‐emitting diodes (OLEDs) comprising triplet‐harvesting emitters require the use of high‐triplet‐energy hosts and blocking layers to confine the triplet excitons to the emitter. Here, we present efficient single‐layer blue hyperfluorescent OLEDs comprising solely of a matrix‐free emissive layer between two charge‐injecting electrodes ...

Broadband Directional Thermal Radiation with Asymmetric Femtosecond Laser‐Processed Surfaces

open access: yesAdvanced Optical Materials, EarlyView.
Femtosecond laser processing is used to scalably create self‐organized angled microstructures which exhibit highly directional emissivity that occurs for all polarizations. Laser parameters are tuned to alter the surface features, control the direction of emission, and enhance the directional emissivity. Electromagnetic modeling is performed to analyze

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
