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).

Strategic construction of fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents for amplifying cancer phototheranostics

open access: yesFlexMat, EarlyView.
The development of conventional phototheranostic nanomedicines suffers from an intrinsic trade‐off between NIR‐II fluorescence emission and phototherapeutic effects, leading to poor overall efficacy. Herein, we propose an innovative fluorination strategy by constructing fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents to ...

Programmable crack dynamics engineering enables flexible strain sensors with high linearity

open access: yesFlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

Chiral supramolecular electronics for high‐efficiency circularly polarized organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
This perspective highlights supramolecular strategy for achieving band‐level chirality in vacuum‐deposited triazatruxene thin films, enabling circularly polarized organic light‐emitting diodes (OLEDs) with both high dissymmetry factor and external quantum efficiency, thereby overcoming the longstanding efficiency‐dissymmetry trade‐off in circularly ...

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 ...
