Abstract
The new amorphous blue light emitting material, which is composed of biphenylenevinylene with α-phenyl as main unit and bulky triphenylsilyl as side units, is designed, synthesized and characterized. The tetraphenylsilane groups of tetrahedral molecular skelecton makes the material have high glass transition temperature of 130 °C and good film quality. Blue organic light emitting device (OLED) employing this compound as the emitter exhibit the maximum luminescence of 4100 cd/m2, the maximum external quantum efficiency of 0.7% and current efficiency of 1.67 cd/A at 12.8 V.
