Abstract

Abstract : We developed an electron‐transport (ET) host material with a novel hetero fused ring which prolongs the lifetime of green phosphorescent organic light‐emitting diodes (OLEDs). We also developed a premixed host containing the ET host and a hole‐transport host. The use of the premixed host can facilitate production of the OLEDs.
