Conjugation‐Induced Thermally Activated Delayed Fluorescence (TADF): From Conventional Non‐TADF Units to TADF‐Active Polymers

Advanced Functional Materials, 2017
Thermally activated delayed fluorescence (TADF)‐type compounds have great potential as emitter molecules in organic light‐emitting diodes, allowing for electrofluorescence with 100% internal quantum efficiency. In small molecules, TADF is achieved through the formation of intramolecular charge‐transfer states.

Thermally Activated Delayed Fluorescence (TADF)‐active Coinage‐metal Sulfide Clusters for High‐resolution X‐ray Imaging

Angewandte Chemie - International Edition
AbstractThe study of facile‐synthesis and low‐cost X‐ray scintillators with high light yield, low detection limit and high X‐ray imaging resolution plays a vital role in medical and industrial imaging fields. However, the optimal balance between X‐ray absorption, decay lifetime and excitonic utilization efficiency of scintillators to achieve high ...

Dimers with thermally activated delayed fluorescence (TADF) emission in non-doped device

Journal of Materials Chemistry C, 2021
Two novel TADF molecules, with donor#1–σ–donor#2–π–acceptor (D1–σ–D2–π–A) conformation, were designed and synthesized through-bond charge transfer (TBCT) and through-space charge transfer (TSCT).

Thermally activated delayed fluorescence (TADF) organic molecules for efficient X-ray scintillation and imaging

Nature Materials, 2021
X-ray detection, which plays an important role in medical and industrial fields, usually relies on inorganic scintillators to convert X-rays to visible photons; although several high-quantum-yield fluorescent molecules have been tested as scintillators, they are generally less efficient.

Nanoencapsulation strategy: enabling electrochemiluminescence of thermally activated delayed fluorescence (TADF) emitters in aqueous media

Chemical Communications, 2021
A water-soluble and air-stable thermally activated delayed fluorescence (TADF) emitter was prepared by a nanoencapsulation strategy, which enables electrochemiluminescence (ECL) of TADF emitters in aqueous media for the first time.

An umpolung strategy for rapid access to thermally activated delayed fluorescence (TADF) materials based on phenazine

Chemical Communications, 2022
Ag(I)-promoted regioselective intramolecular radical nucleophilic addition/rearrangement of 2-aryl diazaboroles has been accomplished to construct phenazine structures, which is an umpolung strategy based on the classical electrophilic mechanism.
