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 ...
