Three highly efficient blue thermally activated delayed fluorescence (TADF) emitters have been synthesized based on pyrimidine, 2-methylpyrimidine and 2-phenylpyrimidine as the acceptor and 10H-spiro[acridan-9,9′-fluorene] as the donor moiety.

We demonstrate a promising molecular design approach to achieve short exciton lifetime, small singlet and triplet energy splitting and high photoluminescence quantum yield in thermally activated delayed fluorescence emitters for high quantum efficiency and low efficiency roll-off characteristics in OLEDs.
