摘要: Abstract A meta- linked diphenylether based host material, 9-(3-(3-(9H-carbazol-9-yl)phenoxy)phenyl)-9H-pyrido[2,3- b ]indole (CzDPEPI), was investigated as an intramolecular charge transfer type material to harvest triplet excitons of phenylimidazole blue Ir emitters. with two carbazole units a reference confirm the role pyridoindole moiety. The CzDPEPI behaved high energy and driving voltage reducing due moiety assisting electron injection improved power efficiency phosphorescent device.
