Preferential Orientation of Vacuum-Processed Host Materials in Phosphorescent Organic Light-Emitting Diodes |
| 초록 |
Vacuum-processed diphenylbis(3-(pyridine-2-yl)phenyl)silane (2PTPS), diphenylbis(3-(pyridine-3-yl)phenyl)silane (3PTPS), and diphenylbis(3-(pyridine-4-yl)phenyl)silane (4PTPS) have been used as electron transporting (ET) host materials combined with tris(4-carbazoyl-9-ylphenyl)amine (TCTA) hole transporting (HT) host, which induce balanced charge carrier transport for high-efficiency phosphorescent organic light-emitting diodes (PHOLEDs). The molecular orientation of TCTA:4PTPS material with narrow azimuthal intensity distribution had better priority to the horizontal direction than the other TCTA:2PTPS and TCTA:3PTPS materials, which is related to the charge transport as well as the device efficiency. |
