Donor‐Substituted C(sp3)‐Bridged Phosphorus‐Heterotriangulenes as Blue Thermally Activated Delayed Fluorescence Emitters

open access: yesAdvanced Optical Materials, EarlyView.
The newly developed regioselective strategy for the para‐functionalization of C(sp3)‐bridged phosphorus‐centered heterotriangulene delivers a series of donor‐acceptor emitters exhibiting thermally activated delayed fluorescence. The carbazole‐substituted compounds feature a unique combination of high photoluminescence quantum yields up to 75%, deep ...

Inverse‐Designed on‐Chip Terahertz Three‐Channel Mode and Wavelength Division Demultiplexer

open access: yesAdvanced Photonics Research, EarlyView.
An ultracompact terahertz demultiplexer is developed using a hybrid inverse design that combines genetic algorithms with topology optimization. The device enables simultaneous mode‐ and wavelength‐division multiplexing within a footprint smaller than two wavelengths.

Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

open access: yesAdvanced Robotics Research, EarlyView.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.
