An Acridine-Carbazole Material

Serves as a host material, hole transport, and electron blocking layer in OLEDs and TADF-OLEDs

9,10-Dihydro-9,9-dimethyl-10-(9-phenyl-9H-carbazol-3-yl)-acridine is a dihydroacridine derivative, also known as PCzAc (CAS number 1705584-08-2).

The dihydroacridine is coupled with 9-phenyl-carbazole, having a high triplet energy of 2.99 eV and a high phase transition temperature of 101 °C. PCzAc exhibits a shallow HOMO level due to the acridine unit.

It is suitable for hole injection between an aromatic amine-type hole transport material and a carbazole-type host material. When it is used as a hole transport material, PCzAc increases the hole density, confines carriers, and broadens the emission zone in the emitting layer. As a result, it improves the lifetime of OLEDs.

PCzAc is also valuable for the development of host materials for europium Eu(II)-based blue spin coated OLEDs, owing to its excellent hole transport properties. The solution-processed OLEDs demonstrate high photoluminescence quantum yields of up to 75%.
