简单介绍


ossila材料SpiroAC-TRZ  的详细介绍
SpiroAC-TRZ (CAS number 1980037-96-4) is designed with a spiroacridine donor covalently linked to a triazine acceptor unit. It functions as a blue-emitting organic semiconductor, exhibiting thermally activated delayed fluorescence (TADF).
SpiroAC-TRZ demonstrates a strong horizontal dipole ratio up to 83% and photoluminescence quantum yield of near 100%. Due to the small singlet-triplet energy gap (ΔEST) of 0.072 eV, the reverse intersystem crossing and related processes readily occur in SpiroAC-TRZ. An OLED device featuring SpiroAC-TRZ shows an extraordinarily high external quantum efficiency of 36.7%, with a current efficiency of 72 cd/A and a power efficiency of 84 lm/W.

As a third-generation OLED emitter, spiroAC-TRZ is also employed in the fabrication of simplified single-layer blue-emitting OLEDs. The emitting layer of SpiroAC-TRZ is situated between ohmic contacts of PEDOT:PSS:PFI anode and Ba/Al cathode. This single-layered OLED exhibits EQE of 27.7% with minimal roll-off, maintaining an EQE of 23% at luminance of 1000 cd/m2.
