Flexible Multi‐Mode Electrochromic Displays for Human Motion Monitoring and Pattern Display in Dark Environments

Exploration, EarlyView.
The reflective nature of electrochromic displays limits their display functionality and human motion monitoring in dark environments. This work presents a flexible multi‐mode electrochromic display (FMECD) with high optical modulation (75.8%) and low energy consumption (0.004% of OLEDs). Integrating EC, PL, and ML functions, it enables continuous, real‐

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.

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

FlexMat, 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).

Spirobifluorene fusion in multiple resonance frameworks enables efficient pure‐red OLEDs with narrowband emission and suppressed efficiency roll‐off

FlexMat, EarlyView.
An orthogonal spirobifluorene‐fusion strategy is introduced for B/N/O‐alternated MR frameworks, enabling improved kRISC (5.46 × 103 s−1), high ΦPL (97%), and narrow‐band pure‐red emission. Vacuum‐evaporated OLEDs incorporating this emitter achieve an EQEmax >40% (FWHM = 36 nm) and exhibit exceptionally low efficiency roll‐off at high luminance ...

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

FlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.
