Taking a snapshot of the triplet excited state of an OLED organometallic luminophore using X-rays

Nature Communications, 2020
OLED materials based on thermally activated delayed fluorescence have promising efficiency. Here, the authors investigate an organometallic multicore Cu complex as luminophore, by pump-probe X-ray techniques at three different facilities deriving a ...

Intramolecular Noncovalent Interactions Facilitate Thermally Activated Delayed Fluorescence (TADF)

The Journal of Physical Chemistry Letters, 2019
In the conventional molecular design of thermally activated delayed fluorescence (TADF) organic emitters, simultaneously achieving a fast rate of reverse intersystem crossing (RISC) from the triplet to the singlet manifold and a fast rate of radiative decay is a challenging task.

Probe exciplex structure of highly efficient thermally activated delayed fluorescence organic light emitting diodes

Nature Communications, 2018
The development of exciplex-type hosts for thermally activated delayed fluorescence organic light-emitting diodes is hindered by a lack of structural information for these donor:acceptor blends.

Regio- and conformational isomerization critical to design of efficient thermally-activated delayed fluorescence emitters

Nature Communications, 2017
The search for brighter emitting materials is essential to the development of OLED devices. Etheringtonet al. show how the presence of two regioisomers of a donor-acceptor-donor thermally-activated delayed fluorescence molecule affects the device ...

Triarylborane-based thermally activated delayed fluorescence materials with an efficient reverse intersystem crossing

Applied Physics Express
Efficient reverse intersystem crossing (RISC) is an important process for thermally activated delayed fluorescence (TADF) to suppress efficiency roll-off in organic LEDs (OLEDs). Enhancing spin–orbit coupling is effective for fast RISC and is achieved by
