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

open access: yesExploration, 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.

Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Non‐fullerene acceptor aggregation regulation via additives dipole moment leads to 19.9% power conversion efficiency in bilayer organic solar cells

open access: yesFlexMat, EarlyView.
Additives interact with non‐fullerene acceptors to modulate their aggregation behavior and molecular orientation via optimizing crystallization kinetics. The optimized morphology effectively suppresses charge carrier recombination and enhances charge transport. Notably, 2‐chloro‐1,3‐dibromobenzene with the dipole moments of 2.56 D enables the PM6/L8‐BO

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

open access: yesFlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...
