We studied the influence on the organic electroluminescent device performance with different DPAVBi position. When DPAVBi was the separate blue light emitting layer and its thickness was 20 nm, the performance of the device is better than others. The yellow light device performance with DPAVBi behind the Rubrene layer is better than the device with it in front of Rubrene layer. The device has a maximum luminous 23560 cd/m2 at 17V and maximum efficiency 6.63cd/A at 16 V. We have received the blue-green light device with the Rubrene doped to DPAVBi. The maximum efficiency is 5.37 cd/A at 9 v and the maximum luminance is 6377 cd/m2 at 16 V. The efficiency drops slowly when the voltage increases. So, all the devices have the current weak fluorescence quenching.

AbstractOrganic electroluminescent(EL) diodes using spin-coat films of cyclohexane-based glass-forming liquid crystal (LC) materials were fabricated. The cyclohexane-based LC materials were found to be useful for EL diodes. Blending the LC materials with charge transport molecules was found to be a promising method for improving device performance. Conventional hole transport and electron transport molecules were found to show a tendency to form exciplexes with cyclohexanebased LC materials. This difficulty was overcome by the introduction of cyclohexane-based charge transport molecules. The EL quantum efficiency of 0.06% was attained in the single-layer devices with two-component blends.
