英文摘要	A binaphthyl derivative with pyrene on 3 and 3' positions was synthesized and characterized via Suzuki coupling reaction. Emission maximum in solution was located at 390 nm with a quantum efficiency of 68% by taking 9,10-diphenyl anthracene as reference, while it is shifted to 450 nm with FWHM of 104 nm resulting from aggregation state in solid film. Glass transition temperature (T-g) and decomposition temperature were measured to be 184 and 447 degrees C, respectively, by DSC and TGA. Unlike its photoluminescence spectrum, electroluminescent spectrum peaked at about 460 nm and shows a FWHM of 69 nm corresponding to a pure blue emission. The turn-on voltage, luminance and efficiency maximum were 5 V, 2953 cd/m(2) and 1.37 cd/A with CIE color coordinate of (0.16, 0.15), in the device structure of ITO/NPB (40 nm)/PY-BN-PY (15 nm)/BPhen (40 nm)/Mg:Ag.
