| 제목 | Highly Efficient Blue Emitting Materials based on Fused Chromophores for OLEDs |
| 초록 | Two related emitting compounds as shown in next page, namely, TP-AFF-TP, TP-ASF were synthesized through typical boration, Suzuki and Sandmeyer reactions. In here, the EL performance was improved by varying the chemical structures of the side groups. Physical properties such as optical, electrochemical, and electroluminescent properties were investigated. Two compounds were used as an EML in OLED device: ITO / 2-TNATA (60nm) / NPB (15nm)/ TP-AFF-TP, TP-ASF (35 nm) / Alq3 (20nm) / LiF (1nm) / Al (200nm). OLED device using TP-AFF-TP showed C.I.E. value of (0.25, 0.45) and luminance efficiency of 2.55 cd/A at 10mA/cm2. TP-ASF device exhibited C.I.E. value of (0.17, 0.31) and high luminance efficiency 5.17 cd/A at 10mA/cm2. It was found that TP-ASF showed better luminance efficiency and better C.I.E. value than TP-AFF-TP device. |
