How to Manufacture Photonic Metamaterials

Advanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Multifunctional Fibrous Mats: Stretchable, Conductive, and Hydrophilic Platforms for Wearable Electronics

Advanced Materials Technologies, EarlyView.
A hydrophilic, stretchable, nonwoven electrospun fiber mat targeted to be applied in long‐term bioelectronic devices. By incorporating amphiphilic polyethylene glycol block copolymers in a polydimethylsiloxane matrix, the material develops stable hydrophilicity, enhanced breathability, as well as enhanced adhesion to cells.

Architected Elastomers as Load Bearing Actuators for Untethered Soft Robot Walking

Advanced Materials Technologies, EarlyView.
Electrically driven soft actuators that enable untethered soft robot walking are developed from 3D printed architected elastomers. The actuators have a handed shearing auxetic structure that enables fast, robust, and battery‐powered motions. The actuators are 3D printed from thermoplastic polyurethane on a desktop FDM printer.

Unveiling Ultrafast Spin‐Valley Dynamics and Phonon‐Mediated Charge Transfer in MoSe2/WSe2 Heterostructures

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study reveals the potential to manipulate spin‐valley polarization dynamics in MoSe2/WSe2 heterostructures by quantifying different scattering processes following selective photoexcitation. The results show that these heterostructures enable ultrafast valley‐selective charge transfer, with phonon scattering playing a significant role in the ...

Self‐Assembly of a Tripodal Terpyridine Based Ligand with Luminescent Lanthanide Ions in Solution and Soft Material

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
The tripodal terpyridine‐1,3,5‐benzene tricarboxamide (BTA) ligand 1 is employed in the self‐assembly formation of novel luminescent materials using a range of lanthanide ions. In the polar protic solution, the results from the photophysical measurements are assessed using nonlinear regression analysis, while the functional material properties of the ...

Polymer Dots Exhibiting Multi‐Resonant Thermally Activated Delayed Fluorescence for Cellular Imaging

Advanced Optical Materials, EarlyView.
By copolymerizing with a host material, a multiple resonance thermally activated delayed fluorescent (MR‐TADF) emitter quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) is successfully assembled into water‐dispersible polymer dots (Pdots). Photophysical measurements and multichannel fluorescence imaging studies show that the narrowband emission from the MR ...

Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

Advanced Optical Materials, EarlyView.
Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...

Simultaneous Emission Spectral Narrowing and Spin‐Flip Acceleration in Multi‐Resonance Organoboron Emitters via Sequential Indolo‐Fusion π‐Extension

Advanced Optical Materials, EarlyView.
Sequential indolo‐fusion π‐extension as a rational design strategy to further narrow the emission bandwidth of multi‐resonance thermally activated delayed fluorescence is introduced. By fusing one or two additional indole moieties to the periphery of Cz‐B, gradual spectra narrowing and accelerated triplet–singlet exciton spin conversion are ...
