An α-Carboline-containing Host Material for High-efficiency Blue and Green Phosphorescent OLEDs

An α-carboline derivative, 9,9′-m-phenylenedi-α-carboline (mCaP) was designed and synthesized as a host material for phosphorescent OLEDs. By using a combination with phosphorescent emitters such as FIrpic and Ir(ppy)3, we have successfully developed high-performance OLEDs with a power efficiency (η...

Zusammenfassung:An α-carboline derivative, 9,9′-m-phenylenedi-α-carboline (mCaP) was designed and synthesized as a host material for phosphorescent OLEDs. By using a combination with phosphorescent emitters such as FIrpic and Ir(ppy)3, we have successfully developed high-performance OLEDs with a power efficiency (ηp,100) at 100 cd m−2 of 37 lm W−1 for blue, and 94 lm W−1 for green, respectively.
