3N-T2T, a versatile transport layer material

Low price and available online for fast and secure dispatch


3N-T2T is a family member of star-shaped 1,3,5-triazine-based electron transport host materials. Further introduction of peripheral pyridyl groups to the triazole core enhances the electron transport/injection properties.

Due to its electron-deficient nature, 3N-T2T can also be used as an electron acceptor, with electron donors such as tris-PCz and DSDTAF to form green exciplexes either as light-emitting active layer or co-host materials.

With a similar chemical structure to TmPyPB, which has a star-shaped 1,3,5-triphenylbenzene core instead, 3N-T2T has a deeper HOMO energy level which could be used as hole blocking layer material.
