Visible‐Light Photoprogrammable Transistors Enabled by an All‐Organic Triplet‐Sensitized Diarylethene Channel Layer

Advanced Optical Materials, EarlyView.
All‐organic channel‐layer OFETs are shown to enable visible‐light photoprogramming via triplet‐sensitized diarylethene switching. Preferential localization of the photoswitch and organic sensitizer in intercrystalline amorphous domains preserves polymer crystalline packing while ensuring short‐range Dexter‐type triplet–triplet energy transfer and solid‐

Quasi‐Random Nanostructured Substrates for Enhancing Light Outcoupling in OLEDs

Advanced Optical Materials, EarlyView.
ABSTRACT Organic light–emitting diodes (OLEDs) suffer from low light outcoupling efficiency, with much of the generated light trapped within the device. To address this issue, we present a scalable, maskless, polymer‐free strategy for fabricating quasi‐random external nanowire (ENW) and internal nanocorrugation (INC) structures directly on glass ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
