Abstract：

The efficiency and lifetime of blue organic light-emitting diodes have been greatly improved for the last several years by developing host and emitters. In our work, we mainly developed high triplet energy hosts for phosphorescent and thermally activated delayed fluorescent emitters to achieve high efficiency and long lifetime at the same time. At the same time, blue thermally activated delayed fluorescent emitters were also developed by engineering the donor-acceptor structure. In this work, I present the molecular design strategy of host and emitters for blue organic light-emitting diodes.
