Small-molecule-based light-emitting materials [Pg.154]

While slightly modifying the former stacking (ITO/PEDOT (35 nm)/QUPD (20 nm)/A,A-6/5 (4-(6-((3-ethyloxetane-3-yl) methoxy) hexylphenyl)-A,jV-diphenylbenzidine OTPD (10 nm)/OTPD Ir l (10 wt.%, [Pg.155]

70 nm)/CsF (2 nm)/Al (100 nm)) by introducing an additional electrontransporting layer between the EML and EIL, luminescence quenching at the cathode could be efficiently suppressed and highly efficient phosphorescent devices were obtained [REH 08], To be solution processable and to avoid the crystallization of 2-(4-biphenyl)-5-(4-tert-butylphenyl)-l,3,4-oxadiazole (PBD) upon drying, the ETL was mixed with 25% poly(methyl methacrylate) (PMMA) to provide a sufficient film-forming ability to the ETL layer. An improvement of the device performance by a factor of 30 was achieved. After optimization of the layers thickness, a maximum CE of 18.4 cd/A and a maximum PE of 15.4 ImAV were obtained with this new device structure. [Pg.156]
