Title: Highly efficient non-doped organic light emitting diodes (OLEDs) using anthracene derivatives with triphenylsilane unit
Abstract: A blue fluorescent emitting material for organic light emitting diodes (OLEDs) based on anthracene derivatives, 10-(4-(triphenylsilyl) phenyl)-9-(10-(4-(triphenylsilyl) phenyl) anthracen-9-yl) anthracene (1), was designed and synthesized via Suzuki coupling reaction. Multilayered OLED was fabricated with a device structure of: ITO (180 nm)/NPB (50 nm)/blue material (30 nm)/Bphen (30 nm)/Liq (2 nm)/Al (100 nm). A device using 1 exhibits high efficiencies (1.85 cd/A, 1.05 lm/W and 0.63% at 100 mA/cm2). Also, the device incorporating 1 shows sky-blue emission with the CIEx,y coordinates of (0.26, 049) at 6.0 V.
