Spiro[acridine-9(10H),9'-[9H]thioxanthene] Usage And Synthesis

Uses

Spiro[acridine-9(10H),9'-[9H]thioxanthene], also known as 10H-spiro(acridine-9,9′- thioxanthene) (TXDMAc), is commonly used in TADF emitter as a donor. The compound BPy3-TXDMAc based on Spiro[acridine-9(10H),9'-[9H]thioxanthene] can be used for OLEDs preparation. In particular, OLEDs employing BPy3-TXDMAc dopant realized maximum external quantum efficiencies (EQEs) up to 25.6%. Moreover, the nondoped device based on BPy3-TXDMAc exhibited a maximum EQE of 18.7%, accompanied by an extremely small efficiency loss of only 4.1% at the luminance of 1000 cd m^-2[1].
