3H-Indole-containing emitters able to realize red fluorescent OLEDs possessing concurrently high efficiencies and good colour coordinates were synthesized through a tautomerization reaction.
In comparison with green and red OLEDs, which have well developed with satisfactory electroluminescence (EL) performances, high-efficiency blue OLEDs still need further exploration. Herein, by reasonably strengthening the rigidity of...
Three new carbazole-based hole-transporting materials PTCz-9’Cz, PTCz-3’TCz, and PTCz-NTol2 were synthesized, characterized, and examined the propensity of exciplex formation with electron-transporting material PO-T2T. Through enhancing the electron-donating ability of the...
The establishment of simple molecular design strategy to realize red-shifted emission while maintaining good color purity for multi-resonance induced thermally activated delayed fluorescent (MR-TADF) materials remains an appealing yet challenging...
Highly efficient host materials for green and red OLEDs were developed via the incorporation of 10,11-dihydro-5H-dibenzo[b,f]azepine as a building block.
