Electron Transport Layer Material with Triazine Core
High purity sublimed electron deficient material for highly efficient TADF-OLEDs
TmPPPyTz (CAS number 939430-31-6), namely 2,4,6-tris(3'-(pyridin-3-yl)biphenyl-3-yl)-1,3,5-triazine, has a wheel-shaped structure with 1,3,5-triazine core and three side arms of 3-pridylbiphenyl, and pyridines on the peripheral. It is highly electron deficient thus used as electron transport layer (ETL), hole blocking layer (HBL) material in highly efficient light-emitting diodes.

wheel shaped molecule
Device with platinum(II) complexes bearing tetradentate ligand with a bridging tertiary amine (tetra-Pt-N) as the active layer material with double-host TCTA:B3PYPM, and B3PYPM as the interlayer between the emissive layer and TmPPPyTz as the electron-transport layer, achieved a maximum power efficiency of over 100 lm/W, a low turn-on voltage of less than 2.5 V and low efficiency roll-off.
TmPPPyTz has a similar structure to 3N-T2T which tends to form exciplex with electron donor as co-host or emitting layer material.
