The plethora of examples contained within this review reveals the versatility of triazine as an acceptor in the design of TADF emitters. By simply varying the strength and number of donors along with the structure of the bridging aryl groups, the emission spectrum can be easily tuned from deep blue through to yellow. The planar conformation adopted by the TRZ moiety can facilitate to the formation of intermolecular exciplexes or through space charge transfer interactions, which enriches the photophysical behavior of these compounds and can contribute to enhancing kRISC.
