Green Dopant Material with Boron-based Carbazoles

High purity sublimed thermally activated delayed fluorescent (TADF) emitter for highly efficient OLEDs


TPA-DCPP (CAS number 1803287-94-6), namely 7,10-bis(4-(diphenylamino)phenyl)-2,3-dicyanopyrazino-phenanthrene is a V-shaped molecule consisting of triphenylamine (TPA) as the donor and 2,3-dicyanopyrazino phenanthrene (DCPP) as the acceptor units.

TPA-DCPP undergoes thermally activated delayed fluorescence (TADF) to emit in the deep red/near-IR region. Nondoped OLED with TPA-DCPP as active layer exhibits a maximum external quantum efficiency (EQE) of 2.1 %, whereas the doped device had an EQE of almost 10 %.
