Effective Manipulation of Water Droplets on Open Superhydrophobic Glass Surfaces by Using a Triboelectrically Charged Polytetrafluoroethylene Rod on the Back Side of These Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
The movement of pure water droplets on a superhydrophobic glass surface is precisely controlled through electrostatic manipulation using a polytetrafluoroethylene (PTFE) rod from the opposite side. With just a few seconds of triboelectric charging, the PTFE rod directs droplets, achieving acceleration over 10 000 mm s−2.

Zinc Chalcogenide Based Shell Layers for Colloidal Quantum Wells

open access: yesAdvanced Materials Interfaces, EarlyView.
A new synthetic route is developed for the synthesis of CdSe/ZnSe/ZnS multi‐shell nanoplatelets (NPLs) with emissions between 615 and 630 nm and photoluminescence quantum yields up to 90%. Control over the lateral size of the starting CdSe core enabled the narrowing of the emission linewidth to 20 nm.

Effective Molecular Alignment of Semiconducting Polymer and Its Application to Photopatterned Stretchable Transistors

open access: yesAdvanced Materials Technologies, EarlyView.
Excellent mobility is achieved in intrinsically stretchable, fine‐patterned organic thin‐film transistors (OTFTs) through well‐aligned molecular arrangements. Abstract Intrinsically stretchable organic transistors are promising solutions for realizing stretchable electronic systems, such as skin‐like wearables and next‐generation displays. Nevertheless,

Suppressed Stokes Shifts and Hot Luminescence from Quantum Dots within Plasmonic Nanocavities

open access: yesAdvanced Optical Materials, EarlyView.
This study demonstrates the suppression of the Stokes shift in lead sulfide quantum dots through integration with plasmonic nanocavities. By enhancing spontaneous emission and altering exciton relaxation pathways, this approach enables direct band‐edge emission with improved radiative efficiency, highlighting the powerful role of nanophotonic ...

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

open access: yesAdvanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Programmable Wide‐Spectrum Complex Microcavity Laser Controlled by Liquid Crystal Elastomer Braking Mechanism

open access: yesAdvanced Photonics Research, EarlyView.
A nematic liquid crystal elastomer (LCE) exhibiting dynamic laser oscillation behavior modulated by mechanical stretching and contraction is synthesized. This study investigates the influence of liquid crystal elastomer deformation characteristics on multidimensional complex microcavity laser systems.

Double‐Sided Control of Product Type Preference in the Visible‐Light Initiated Reaction of 1,3‐Dicarbonyl Compounds with Alkenes

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract The demonstrated light‐initiated addition of radicals formed on an active methylene group to styrene derivatives exhibits a product selectivity influenced by the presence of a protic solvent. Under protic conditions, the predominant products are branched compounds with the alkene moiety attached to the methylene group.
