| 제목 | Synthesis and Property of New Blue Emitting Materials based on Anthracene with Bulky Side Group |
| 초록 | Two related emitting compounds as shown in next page, namely, 9,10-Bis-[1,1';3',1'']terphenyl-5'-yl-1,5-di-o-tolyl-anthracene [TP-DTA-TP] and 9,10-Bis-[1,1';3',1'']triphenylbenzene-5'-yl-1,5-di-o-tolyl-anthracene [TPB-DTA-TPB] were synthesized through typical boration, Suzuki and Sandmeyer reactions. Two compounds and DTA were used as an EML in OLED device: ITO / 2-TNATA (60nm) / NPB (15nm)/ DTA or TP-DTA-TP or TPB-DTA-TPB (35 nm) / Alq3 (20nm) / LiF (1nm) / Al (200nm). OLED device using TP-DTA-TP showed C.I.E. value of (0.36, 0.53) and luminance efficiency of 3.58 cd/A at 10mA/cm2. TPB-DTA-TPB device exhibited C.I.E. value of (0.17, 0.23) and high luminance efficiency 4.85 cd/A at 10mA/cm2. It was found that TPB-DTA-TPB showed better luminance efficiency and better C.I.E. value than TP-DTA-TP device because it had the increased size of side group. |
