Abstract/OtherAbstract:
A series of seven diarylaminofluorene-derived fluorescent molecules demonstrating a blue emission in organic light-emitting diodes (OLEDs) were synthesized via the Horner-Wadsworth-Emmons reaction and the Suzuki-cross coupling reaction. Among the molecules, one device exhibited blue emission with a maximum luminance of 28900 cd/m2 at 12 V. A luminous efficiency of 11.5 cd/A at 20 mA/cm2 was achieved. The peak wavelength of the electroluminescence (EL) was 459.5 nm with the CIE coordinates of (x = 0.173, y = 0.281) at 8 V. The device also showed a stable color chromaticity at various voltages.
