A series of blue fluorescent materials based on asymmetric mono-triphenylamine-substituted anthracenes have been synthesized and characterized using spectroscopic analysis. Multilayered organic light-emitting diodes (OLED) were fabricated using these materials as dopants. A maximum luminance of 27900 cd/m(2) at 11 V and a luminous efficiency of 10.1 cd/A at 20mA/cm(2) were achieved. The peak wavelength of the electroluminescence was 459 nm with CIE coordinates of (0.174, 0.288) at 10 V and the device also showed a stable color chromaticity at various voltages.
