Highly efficient blue as well as green, yellow and host for red phosphorescent emitter, 2,4,6-tris(2-(1H-pyrazol-1-yl)phenyl)-1,3,5-triazine (3P-T2T), CAS 352196-01-1

3P-T2T, 2,4,6-tris(2-(1H-pyrazol-1-yl)phenyl)-1,3,5-triazine, has a structure with an electron deficient triazine core equipped with phenylpyrazole peripherals. Like PO-T2T and 3N-T2T, 3P-T2T is one of the triazine derivatives and is normally used as an electron transport layer (ETL) in OLED devices. 3P-T2T shows a higher electron transport/injection ability than T2T due to the peripheral three electron-withdrawing pyrazolyl moieties.

As an acceptor, together with TCTA as hole transporting donor, 3P-T2T forms exciplex as a highly efficient yellow delayed fluorescent emitter. The exciplex TCTA:3PT2T has high and balanced hole and electron mobilities and large energy-levels offsets at the TCTA/3P-T2T interface.

3P-T2T can not only accommodate highly efficient blue, but can also act as suitable host for green, yellow and red phosphorescent emitters.
