We designed and synthesized triplet-triplet fusion type hosts for Blue fluorescent organic light-emitting diodes mobility using anthracene moiety. The triplet-triplet fusion type host materials were synthesized by one step and the reaction yield was around 64.5, 58.0%, respectively. The HOMO level of materials was measured as -6.06, -6.01 eV and the LUMO level of materials was measured as -3.36, -2.95 eV, respectively. And this materials were evaluated by fabricating single layer device. Device property results showed that evaluated material had enhanced external quantum efficiency. This work demonstrated that newly synthesized triplet-triplet fusion type anthracene derivatives were effective for Blue fluorescent organic light-emitting diodes. |
