Blue thermally activated delayed fluorescent (TADF) emitters were developed by linking a donor moiety to a triazine core via the ortho-position of an aromatic moiety. Three phenylcarbazole derivatives with different substituents were incorporated into the 4,6-diphenyltriazine core to prepare the blue TADF emitters. The photophysical properties and device performance of the blue TADF emitters were investigated, and the blue TADF emitters with 3,6-dimethyl-9-phenylcarbazole as the donor moiety showed a high quantum efficiency of 14.7%.
