The Golden Age of Thermally Activated Delayed Fluorescence Materials: Design and Exploitation. [PDF]

Chem Rev
Since the seminal report by Adachi and co-workers in 2012, there has been a veritable explosion of interest in the design of thermally activated delayed fluorescence (TADF) compounds, particularly as emitters for organic light-emitting diodes (OLEDs).

Thermally Activated Delayed Fluorescence in Fullerenes [PDF]

Annals of the New York Academy of Sciences, 2008
This report reviews the thermally activated delayed fluorescence (TADF) displayed by fullerenes. From the analysis of the steady‐state data, time‐resolved data, or by a combination of both, it is possible to determine several important photophysical parameters of fullerenes.

Lock-and-Key Exciplexes for Thermally Activated Delayed Fluorescence

Organic Materials, 2020
We combine synthetic supramolecular chemistry and materials science to develop novel exciplexes for thermally activated delayed fluorescence. Our approach starts from a bowl-shaped acceptor molecule for which we synthesize tailor-made donors that bind in

Donor–Acceptor Iptycenes with Thermally Activated Delayed Fluorescence [PDF]

European Journal of Organic Chemistry, 2017
A new donor–acceptor iptycene containing carbazole donors and a thiadiazoloquinoxaline acceptor was synthesized and its photo‐ and electrochemical properties evaluated. The key intermediate 1 allows a lateral modification through cross‐coupling, and the (triisopropylsilyl)acetylene product 2 exhibits bright yellow fluorescence with emission lifetimes ...
