A Novel Linking Strategy of Using 9,10‐Dihydroacridine to Construct Efficient Host Materials for Red Phosphorescent Organic Light‐Emitting Diodes

Abstract: Three novel 9,10-dihydroacridine derivatives, 4'-(10-methyl-9,9-diphenyl-9,10-dihydroacridin-4-yl)[1,1'-biphenyl]-4-carbonitrile (MeAcPhCN), 4'-(9,9,10-triphenyl-9,10-dihydroacridin-4-yl)[1,1'-biphenyl]-4-carbonitrile (PhAcPhCN), and 5-[4-(9,9,10-triphenyl-9,10-dihydroacridin-4-yl)phenyl]picolinonitrile (MeAcPyCN), were prepared by the attachment of [1,1'-biphenyl]-4-carbonitrile or 5-phenylpicolinonitrile to the 4-position of 9,10-dihydroacridine. This special linking strategy limited the conjugation length, … Show more

“…[10][11][12][13] Few cases report its use in hosts for red phosphorescence OLEDs. 14,15 Furthermore, what brought our attention to the acridine group is that it has a higher triplet energy than carbazole (due to less conjugation). 16 The pyrimidine unit is also a building block for TADF emitters due to its acceptor (A) properties.…”
