Facet‐Specific PbS Quantum Dot Passivation Using Halide Perovskites for SWIR Photodetectors

Advanced Materials Interfaces, EarlyView.
PbS quantum dots (QDs) are emerging as powerful short‐wave infrared photodetectors, yet the passivation mechanism of large QDs by perovskites ‐ critical for their stability ‐ remains unexplained. Here, we unveil the ligand structure of CH3NH3PbI3 (MAPI)‐passivated 4‐nm PbS QDs using FTIR, XPS, SEM, NMR, and DFT.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Mitigating Efficiency Roll‐Off in Phosphor‐Sensitized Fluorescence OLEDs via Molecular Polarity‐Based Benzofuropyridine Host Engineering

Advanced Optical Materials, EarlyView.
Positional isomerism in dibenzofuran‐based n‐type hosts modulates molecular polarity, charge‐transport balance, and emissive‐layer packing. The higher‐polarity BFPDB‐2 host facilitates efficient energy funneling, reduced aggregation, and preferential dipole orientation, leading to phosphor‐sensitized fluorescence OLEDs with enhanced external quantum ...

Naphthyridine‐Based Donor–Acceptor Boron Difluoride Complexes Targeting Red Emission in Organic Light‐Emitting Diodes

Advanced Optical Materials, EarlyView.
Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

A Proline‐Integrated Donor–Acceptor Fluorophore: Water‐Vapor‐Responsive Mechanochromic Luminescence and Latent Fingerprint Visualization

Advanced Optical Materials, EarlyView.
A proline‐integrated donor–acceptor fluorophore enables multifunctional luminescence through rational molecular design. Water‐vapor‐responsive mechanochromic luminescence (MCL) with circularly polarized luminescence (CPL) switching and efficient visualization of latent fingerprints (LFPs) are realized from this single small organic molecule.
