Synthesis and Electroluminescence Properties of New Blue Dual-Core Emitters Using Spirofluorene and Phenylcarbazole |
| 초록 |
We used spirofluorene and carbazole as the side groups and substituted them into a 1-anthracen-9-yl-pyrene (AP) dual core. DSF-AP and SCP-AP were synthesized through borylation and the Suzuki aryl-aryl coupling reaction. Synthesized materials exhibited PLmax values at 443 nm and 448 nm in solution state (CHCl3), and at 458 nm and 463 nm in a thin-film state. Electroluminescence (EL) devices with the synthesized materials were fabricated. Compared with the EL device of AP core, EL device of DCP-AP showed 31% higher luminance efficiency (resulting in a value of 4.37 cd/A) and 32% higher power efficiency (to yield 1.93 lm/W), as well as a high external quantum efficiency (3.64%). |
