Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

FlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.

Meniscus‐guided organic semiconductor single crystals: From fluid dynamics to morphology control and multifunctional applications

FlexMat, EarlyView.
Centered on the multiscale meniscus, this review dissects mass transport in meniscus‐guided coating into parallel and lateral components. By analyzing the balance of multiple factors during crystallization, it establishes a clear morphology‐performance relationship.

Challenges and strategies toward next‐generation high‐performance flexible and printable thin‐film transistors

FlexMat, EarlyView.
This review explores recent progress in printing strategies such as inkjet, screen, liquid metal, and roll to roll (R2R) methods and their roles in fabricating flexible TFTs. Device architectures are examined with emphasis on printed components and their influence on performance and stability.

Pyridine‐dicarbonitriles acceptor engineering in multi‐resonance thermally activated delayed fluorescence with hybridized short‐ and long‐range charge transfer for high‐performance electroluminescence

FlexMat, EarlyView.
Pyridine‐dicarbonitrile units integrated into a multiple‐resonance core engineer the excited state through cooperative short‐range charge transfer (SRCT) and long‐range charge transfer (LRCT), thereby enhancing the spin‐flipping process. Abstract Multi‐resonance (MR) thermally activated delayed fluorescence (TADF) materials exhibit narrowband emission ...

Diboron‐Embedded Heteroacenes With Systematically Varied Central π‐Skeletons and Fusion Modes

Helvetica Chimica Acta, EarlyView.
We synthesized diboron‐embedded acenes and revealed that fusion mode governs electronic properties, whereas molecular symmetry dictates crystal packing. One C2v‐symmetric isomer forms a uniform columnar π‐stacked array. ABSTRACT Diboron‐embedded heteroacenes with systematically varied central π‐skeletons and fusion modes were synthesized via one‐pot ...
