Optical and Electroluminescence Properties of Highly Efficient Dual Core Chromophores with Aromatic Amine Side Groups |
| 초록 |
This study substituted diphenyl amine(DPA) and triphenyl amine(TPA), which are different in size, with side groups and systematically changed their position in a dual core composed of anthracene and pyrene to synthesize blue emitting materials with asymmetric or symmetric structures. The study synthesizes DPA-AP-TP, TPA-AP-TP, TP-AP-DPA and TP-AP-TPA, as the structures asymmetric with 1-Anthracen-9-yl-pyrene (AP-core), a dual core, and DPA-AP-DPA and TPA-AP-TPA as those symmetric with AP-core. Among synthesized compounds, TPA-AP-TP which TPA side group was substituted in anthracene showed the highest EL device efficiency as 8.05 cd/A and exhibited sky blue emission of CIE (0.14, 0.24). |
