Two blue thermally activated delayed fluorescence molecules based on bis(phenylsulfonyl)benzene with very small singlet-triplet splitting energy were designed and synthesized by combining 3,6-di-tert-butylcarbazole with 1,4-bis(phenylsulfonyl)benzene and 1,3-bis(phenylsulfonyl)benzene, and a maximum external quantum efficiency of 11.7% was achieved for an electroluminescent device.
[reaction: see text] Dendron-encapsulated materials having a benzo[c][1,2,5]thiadiazole-based red-emitting core and p-type and/or n-type peripheries were synthesized. Intra- and intermolecular energy transfer from the peripheries to the core were found to be peripheries dependent. Red-emitting electroluminescent devices with promising performance were fabricated.
