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.

Phosphorescent materials, IR-FPPA1, IR-PPA1 and IR-TPA1 as emission dopants for electroluminescent (EL) devices were synthesized. Three types of devices such as ITO/ NPD/IR-FPPA1 (6%), IR-PPA1 (6%) and IR-TPA1 (6%) in CBP/BCP/Alq/LiF/Al were fabricated. IR-FPPA1, IR-PPA1 and IR-TPA1 exhibited 540 Cd/m2, 6600 Cd/m2 and 590 Cd/m2 with their external quantum efficiency of 1.2%, 8.9% and 3.0% in current densities of 20 mA/cm2, respectively. EL spectra of the IR-FPPA1, IR-PPA1, and IR-TPA1 devices had the band maxima at 490 nm, 535 nm and 615 nm, respectively.
