Abstract
A novel blue emitter, In2Bt, featured with a rigid and coplanar distyryl-p-phenylene backbone flattened by two different bridging atoms (i.e. carbon and sulfur) exhibits high thermal and morphological stability (Tg ∼ 192 °C) and ambipolar charge carrier mobilities in the range of 10-4 ∼ 10-5 cm2 V-1 s-1. OLED device: ITO/PEDOT:PSS (300 Å)/α-NPD (200 Å)/TCTA (100 Å)/In2Bt (200 Å)/TPBI (500 Å)/LiF (5 Å)/Al (1500 Å) utilized In2Bt as an emitter gave a maximum brightness as high as 8000 cd m-2 (12 V) and saturated-blue emission with CIE chromaticity coordinates of (0.16, 0.08), which is very close to the National Television Standards Committee (NTSC) standard blue gives an enlarged palette of colors for color displays. © 2008 Elsevier B.V.
