Three bipolar blue fluorescent materials were newly synthesized by attaching diphenylamine (DPA), triphenylamine (TPA), and 9-phenylcarbazole amine (PCA) as an electron donating group and 2,4- diphenyl-1,3,5-triazine (DPT) as an electron withdrawing group to the dual anthracene core moiety. Compounds are [10’-(4,6- Diphenyl-[1,3,5]triazin-2-yl)-[9,9’]bianthracenyl-10-yl]-diphenyl-amine (DPA-AA-DPT), {4-[10’-(4,6-Diphenyl-[1,3,5]triazin-2-yl)-[9,9’]bianthracenyl-10-yl]- phenyl}-diphenyl- amine (TPA-AA-DPT), and 9-(4-(10’-(4,6-diphenyl-1,3,5-triazin-2-yl)-[9,90 -bianthracen]-10-yl)phenyl)- 9H-carbazole (PCA-AA-DPT), respectively. The optical, thermal, and electroluminescence (EL) properties of the synthesized materials were measured. Newly bipolar materials were found to have blue emission in the solution state and to acquire high PLQY values. |
