A traveling wave decelerator for neutral polar molecules [PDF]

, 2011
Recently, a decelerator for neutral polar molecules has been presented that operates on the basis of macroscopic, three-dimensional, traveling electrostatic traps (Osterwalder et al., Phys. Rev. A 81, 051401 (2010)).

Intramolecular FRET Cascades Enable Small Efficiency Roll‐Off in Solution‐Processed OLEDs

Advanced Optical Materials, EarlyView.
This work highlights how an intramolecular FRET design strategy in solution‐processable MR‐TADF emitters enables narrowband emission, high PLQY, and efficient exciton harvesting. The resulting hyperfluorescent solution‐processed OLEDs reach up to 20.7% EQEmax with minimal efficiency roll‐off even at 10 000 cd m−2, demonstrating strong potential for ...

Highly Efficient Mechanochromic Thermally Activated Delayed Fluorescence in the Deep Red to Near‐Infrared in Copper(I) [2.2]Isoindolinophanyl‐Carbene Carbazolates

Angewandte Chemie, EarlyView.
Electrophilic [2.2]isoindolinophanyl‐based carbene iPC has been employed as charge‐transfer acceptor ligand in a series of [Cu(iPC)(carbazolate)], which show mechanochromism and environment‐dependent luminescence due to intermolecular C─‐H‐π interactions.

Stepwise taming of triplet excitons via multiple confinements in intrinsic polymers for long-lived room-temperature phosphorescence

Nature Communications, 2023
Polymeric materials exhibiting room temperature phosphorescence (RTP) show a promising application potential. However, the conventional ways of preparing such materials are mainly focused on doping, which may suffer from phase separation, poor ...

General Approach To Compute Phosphorescent OLED Efficiency

, 2018
Phosphorescent organic light-emitting diodes (PhOLEDs) are widely used in the display industry. In PhOLEDs, cyclometalated Ir(III) complexes are the most widespread triplet emitter dopants to attain red, e.g., Ir(piq)3 (piq = 1-phenylisoquinoline), and ...

Visible‐Light Sensitized Isomerization in the Lipid Bilayer Enables Activation of a Transmembrane Transporter

Angewandte Chemie, EarlyView.
A stiff‐stilbene‐based transmembrane anion transporter is isomerized by energy transfer from a ruthenium tris(bipyridyl) photosensitizer in the lipid bilayer. This sensitized isomerization allows activation of chloride transport using visible instead of UV light, without the need to chemically modify the stiff‐stilbene photoswitch.
