Tetracyclic π‐Extended Multi‐Resonant TADF Emitters for Green PSF‐OLEDs With 37.7% EQE and BT.2020‐Compatible Top‐Emitting Devices

Advanced Functional Materials, EarlyView.
Ultra‐narrow green multi‐resonance thermally activated delayed fluorescence emitters have been developed by linear π‐extension strategy using tetracyclic naphtho[2,3‐b]benzofuran unit. The resulting phosphorescence‐sensitized OLEDs achieve a maximum external quantum efficiency of 37.7% in the bottom‐emitting architecture, while the complementary top ...

Chemical Constituents of the Deep-Sea-Derived Fungus Talaromyces wortmannii and Their Ferroptosis Inhibitory Activity. [PDF]

Chem Biodivers
One new tyramine derivative (1) and 28 known compounds (2–29) were isolated from deep‐sea‐derived fungus Talaromyces wortmannii. Their structures were elucidated by NMR/MS and computational calculations. Compounds 2 and 6 potently inhibited ferroptosis with EC5₀ values of 4.52 and 13.73 µM.

Structural Insights into the TES/TFA Reduction of Differently Substituted Benzofurans: Dihydrobenzofurans or Bibenzyls?

, 2021
Various polysubstituted benzofurans were reduced by using triethylsilane in trifluoracetic acid. 2,3-Dihydrobenzofurans or bibenzyl compounds were obtained in high yields, depending on the nature of the substituents at C2 and on the benzene ring of the ...
