A Computational Descriptor Analysis on Excited State Behaviours of a Series of TADF and Non-TADF Compounds [PDF]

Physical Chemistry Chemical Physics, 2021
The thermally activated delayed fluorescence (TADF) behaviours of seventeen organic TADF emitters and two non-TADF chromophores bearing various donor and acceptor moieties were investigated, focusing on their torsion angles, singlet-triplet gap (ΔEST ...

Maximizing TADF via Conformational Optimization [PDF]

The Journal of Physical Chemistry A, 2021
We investigate a new strategy to enhance thermally activated delayed fluorescence (TADF) in organic light-emitting diodes (OLEDs). Given that the TADF rate of a molecule depends on its conformation, we hypothesize that there exists a conformation that ...

Strongly Luminescent Tetradentate Palladium(II)‐TADF Emitters. Blue TADF And TADF‐Sensitized OLEDs with External Quantum Efficiencies Over 23%

Advanced Optical Materials, 2023
Due to the low-lying Pd(4d)-orbitals, luminescent palladium(II) complexes usually show 3IL phosphorescence (IL = intraligand) with excited state lifetimes in the range of hundreds of microseconds, which limits their application in blue organic light ...

TADF Dye-Loaded Nanoparticles for Fluorescence Live-Cell Imaging

Frontiers in Chemistry, 2020
Thermally activated delayed fluorescence (TADF) molecules offer nowadays a powerful tool in the development of novel organic light emitting diodes due to their capability of harvesting energy from non-emissive triplet states without using heavy-metal ...

What Controls the Orientation of TADF Emitters? [PDF]

Frontiers in Chemistry, 2020
Thermally-activated delayed fluorescence (TADF) emitters—just like phosphorescent ones—can in principle allow for 100% internal quantum efficiency of organic light-emitting diodes (OLEDs), because the initially formed electron-hole pairs in the non-emissive triplet state can be efficiently converted into emissive singlets by reverse intersystem ...

Photoactivation-Enabled Tunable Room-Temperature Phosphorescence and Thermally Activated Delayed Fluorescence in Crystalline Materials. [PDF]

Adv Sci (Weinh)
This work is the first to demonstrate the regulation of photoactivated room‐temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) in crystalline materials without any pretreatment. Furthermore, we reveal the underlying mechanisms by uncovering the role of host‐guest energy level alignment, exciton lifetime, crystallinity,
