- Novel platinum complex of porphyrin with methyl and cyclohexyl substituents, PtMECHP, was designed and synthesized for use as a red phosphorescent material. PtMECHP was employed as an emission dopant in the OLED and the elctro-optical characteristics were investigated. The OLED was fabricated by vacuum deposition, and the layer-structure of device was ITO/NPD/PtMECHP(10%) in CBP/BCP/Alq/LiF/Al to exhibit brightness of 53 cd/m2 at 11 mA/cm2 and the external quantum efficiency of 1.2% at the same current density. The maximum EL band was detected at 650 nm with red phosphorescence. © 2007 Elsevier B.V. All rights reserved.
