High PLQY efficiency and purity, 2-phenyl-4'-carbazole-9H-thioxanthen-9-one-10,10-dioxide, CAS No. 1623010-64-9, Sublimed ≥99.0%

TXO-PhCz is a TADF green emitter with a typical D-A structure consisting with electron withdrawing thioxanthone and electron-donating phenylcarbazole units.

The D-A moieties of TXO-PhCz is angularly linked to provide effective separation of electron densities of the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) in a single molecule.

Small ΔEST of 73 meV for TXO-PhCz is observed resulting efficient reversed intersystem crossing (RISC) and then high photoluminescence quantum yield (PLQY) efficiency.
