Antibacterial Hydrogel Dressing With Ca2+‐Dependent Hyaluronidase Responsiveness for Accelerating Wound Healing via On‐Demand Release of AIE Photosensitizers

Exploration, EarlyView.
This study innovates a Ca2+‐responsive hydrogel dressing that releases AIE photosensitizers on‐demand. Low Ca2+ enhances bacterial hyaluronidase (HAase) activity, degrading hyaluronic acid dressing to trigger antibacterial ROS release, while high Ca2+ inhibits HAase, preventing overdosing.

Visible Photosensitizing Disinfectant Spray for Combating Multidrug‐Resistant Candidozyma Auris in Healthcare Settings

Exploration, EarlyView.
We designed and synthesized a dual‐type AIE photosensitizer (named TB) spray, containing a cationic quaternary ammonium unit and a glycosyl‐targeted boronic acid moiety, characterized for the elimination of biofilm infections of Candidozyma auris (C. auris) on high‐touch surfaces.

Blue‐hazard‐free single‐emissive‐layer white organic LEDs based on an anti‐quenching narrowband blue emitter

FlexMat, EarlyView.
A blue‐hazard‐free single‐emissive‐layer white OLED is realized using an anti‐quenching multiple‐resonance TADF emitter, BNCT. By integrating a sterically protected MR core with efficient energy transfer capability, BNCT enables warm‐white emission with high efficiency, negligible hazardous blue photons, and a simplified device architecture for next ...

Thermally activated delayed fluorescence exciplex sensitizers with fast reverse intersystem crossing for improving efficiency stability of organic light‐emitting diodes based on multi‐resonance emitters

FlexMat, EarlyView.
Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

A trade‐off between efficiency and stability in a class of sky‐blue organic light‐emitting diodes

FlexMat, EarlyView.
OLED efficiency and stability are correlated with device structure using combined experimental and simulation approach. Efficient, but less stable devices suffer mainly from exciton‐exciton annihilation, while their opposites have excitons predominantly quenched by polarons.
