Aryl-substituted acridanes as hosts for TADF-based OLEDs
Beilstein J. Org. Chem. 2020, 16, 989–1000, doi:10.3762/bjoc.16.88
- ”, 202 Stryska Str. 79031, Lviv, Ukraine 10.3762/bjoc.16.88 Abstract Four aryl-substituted acridan derivatives were designed, synthesized and characterized as electroactive materials for organic light emitting diodes based on emitters exhibiting thermally activated delayed fluorescence. These compounds
- demonstrated maximum external quantum efficiencies up to 3.2%. Keywords: acridan; hole mobility; host; OLED; thermally activated delayed fluorescence; Introduction Organic light emitting diodes (OLEDs) are perfect candidates for multicolor displays and for next generation energy saving large area-lighting
- levels are overcome [22][23][24][25][26]. The only hole or electron-transporting property of hosts leads to charge recombination near the interface between the charge-transporting layer and the emissive layer, thus decreasing the device’s efficiency [27]. In this work, four acridan derivatives were
Recent advances on organic blue thermally activated delayed fluorescence (TADF) emitters for organic light-emitting diodes (OLEDs)

- % could be attained for the sky-blue B4-based devices. Still based on the combination of acridan and 10H-phenoxaborin units, a complete isolation of the two units could be realized in B6 by directly functionalizing the 10H-phenoxaborin core with a spiro-type acridan group [38]. Using this strategy, pure
- aromatic ring, interrupting the π-conjugation and localizing the HOMO level on the acridan moiety and the LUMO level on the central accepting group. The calculations also predicted a more planar phenyl–pyrimidine/phenyl–pyridine conformation (i.e., a smaller dihedral angle) in CN-P5/CN-P4 and a more
