Highly efficient matrix-free hyperfluorescent organic light-emitting diodes are constructed with remarkably supressed Dexter transfer utilizing narrowband blue emitters encapsulated with hopped alkyl chains.

The device performance of pure-green hyperfluorescent organic light-emitting diodes remains unsatisfactory. Here, the authors report multi-resonance emitters with extended π−conjugation or increased donor strength, resulting in bright, efficient and stable pure-green hyperfluorescent devices.

Photo-responsive metal halide perovskite light-emitting diodes can be used to create a multifunctional display that can function as a touch screen, ambient light sensor and image sensor.

We report a crystalline host matrix with engineered nanoaggregate structure for fabricating high-performance crystalline white OLEDs (C-WOLED), showing its significant potential in developing the next-generation OLED technology.

It has been challenging to realize efficient and stable blue phosphorescent organic light-emitting diodes. Here, authors explore the effect of substitution position in platinum(II) dopants with suppressed metal-metal-to-ligand charge transfer features, resulting in prolonged lifetime in the devices.

The realization of a BT.2020 blue emitter is challenging due to the spectral redshift associated with π-extension. Here, the authors report a multi-resonance thermally activated delayed fluorescence emitter, exhibiting ultrapure deep-blue narrow emission and CIEy ≤ 0.05 exceeding 20% efficiency.

Efficiency roll-off in a wide range of TADF OLEDs is analysed and a figure of merit proposed for materials design to improve efficiency at high brightness, potentially expanding the range of applications of TADF materials.

Highly efficient matrix-free hyperfluorescent organic light-emitting diodes are constructed with remarkably supressed Dexter transfer utilizing narrowband blue emitters encapsulated with hopped alkyl chains.

Organic π-conjugated radicals have recently joined the ranks of high-efficiency light-emitting materials, however, their light-emission mechanism is still a matter of debate. Here, the authors highlight a recently proposed luminescent enhancement mechanism and record-breaking efficiency of a radical organic light-emitting diode.

An article in Advanced Materials reports molecules designed following the A-D-A′-D-A structure that exhibit efficient emission beyond 1,100 nm.

Suppression of exciton–vibration coupling yields organic light-emitting diodes that emit at 1,000 nm in the NIR-II spectral region, which is important for biological imaging.

Next-generation light-emitting displays should be not only flexible and bright but also soft and stretchable. Newly emerging light-emitting materials will enable body-conformable light-emitting devices with potential applications in a variety of fields, including displays, lighting, sensing, imaging, stimulation and therapy.
