摘要：
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 (T-g similar to 192 degrees C) and ambipolar charge carrier mobilities in the range Of 10(-4)similar to 10(-5) cm(2) V-1 s(-1). OLED device: ITO/PEDOT:PSS (300 angstrom)/alpha-NPD (200 angstrom)/TCTA (100 angstrom)/In2Bt (200 angstrom)/TPBI (500 angstrom)/LiF (5 angstrom)/Al (1500 angstrom) 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.
