Derivatives of 1,5-Diaza-bicyclo[3.3.1]nonane with anthracene substituents at ortho or para position of phenyl rings were synthesized. And Organic Linght Emitting Devices were fabricated with these materials as non-doped emitting layer. The effects of substituted anthracene substituents have been compared based on both materials and solid device evaluation. Its optical and electroluminescent properties were investigated. Three compounds were used as emitting layer (EML) in OLED device: ITO / 2-TNATA (60nm) / NPB (15 nm) / synthesized materials (30 nm) / Alq3 (20 nm) / LiF / Al. The luminance efficiency of the synthesized compound at 10mA/cm2 were measured 1.56cd/A for Ph-o-21 and 0.28cd/A for Ph-o-20 respectively. Moreover, the power efficiency were measured 1.08lm/W for Ph-o-21 and 0.09lm/W for Ph-o-20. The device, prepared by using the anthracene-substituted material at ortho position, showed the better performance with CIE(x,y)=(0.28,0.45). |
