TCzTRZ, high purity TADF sky blue emitter
Paired with the donor DMAC-DPS, the device can achieve high PLQY and quantum efficiency
TCzTRZ - 9,9',9''-(5-(4,6-Diphenyl-1,3,5-triazin-2-yl)benzene-1,2,3-triyl) tris(9H-carbazole) is a TADF sky blue emitter with an electron deficient triphenyltriazine and three electron donating carbazole moieties.
Blue emitting DMAC-DPS as donor and TCzTrz as acceptor can form highly efficient exciplex, resulting in high photoluminescence quantum yield and high quantum efficiency in the green exciplex organic light-emitting diodes.
