Thermally Activated Delayed Fluorescent (TADF) Mono‐Polymeric OLED with Higher EQE over Its TADF Repeating Unit

Macromolecular Chemistry and Physics, 2022
AbstractThermally activated delayed fuorescent (TADF) polymers are very suitable for fabricating highly efficient solution‐processed organic light emitting diodes (OLEDs). TADF homopolymers with simple structures are much preferred for preparation, but due to the triplet–triplet annnihilation, most TADF homopolymeric OLED exhibits lower external ...

High Efficiency Sky‐Blue Gold(III)‐TADF Emitters**

Chemistry – A European Journal, 2020
AbstractHighly efficient sky‐blue luminescent gold(III) complexes with emission quantum yields up to 82 %, lifetimes down to 0.67 μs and emission peak maxima at 470–484 nm were prepared through a consideration of pincer gold(III) donor–acceptor complexes.

Exciplex: An Intermolecular Charge-Transfer Approach for TADF

ACS Applied Materials & Interfaces, 2018
Organic materials that display thermally activated delayed fluorescence (TADF) are a striking class of functional materials that have witnessed a booming progress in recent years. In addition to pure TADF emitters achieved by the subtle manipulations of intramolecular charge transfer processes with sophisticated molecular structures, a new class of ...

Understanding the Fluorescence of TADF Light-Emitting Dyes

The Journal of Physical Chemistry A, 2016
In order to afford in a controlled fashion fine-tuning of the color and the intensity of the emitted light of potential fluorophores for organic light-emitting diodes (OLED), directed molecular design based on a donor-spacer-acceptor model is undertaken. One way of increasing emission efficiency is triplet harvesting.

Outstanding Circularly Polarized TADF in Chiral Cu(I) Emitters: From Design to Application in CP‐TADF OLEDs

Angewandte Chemie
AbstractLow‐cost molecular emitters that merge circularly polarized luminescence (CPL) and thermally activated delayed fluorescence (TADF) properties are attractive for many high‐tech applications. However, the design of such emitters remains a difficult task.

Potential TADF Structures with Benzophenone Moieties

2019
The architectures of organic solar cells are based on two kinds of materials: electron donors (D) and electron acceptors (A), respectively. Organic compounds which possess donor-acceptor units exhibit important optical and photophysical characteristics.

Intermolecular interaction approach for TADF (Conference Presentation)

Organic Light Emitting Materials and Devices XX, 2016
Materials with thermally activated delayed fluorescence (TADF) have recently emerged as new fluorescent emitters for highly efficient organic light-emitting diodes (OLEDs). Molecule with TADF behavior needs to have a small singlet–triplet energy difference (ΔES-T) that allows the up-conversion from nonradiative triplet state (T1) to radiative singlet ...
