TCPZ, bipolar host to create highly efficient devices with ultra-low driving voltages

For high performance deep-red, green and blue PhOLEDs

TCPZ - 2,4,6-Tris(3-(9H-carbazol-9-yl)phenyl)-1,3,5-triazine is a bipolar host with an electron withdrawn triphenyltriazine centre and three electron rich carbazole peripheral units.

With its decreased singlet–triplet exchange energy (ΔEST = 0.24 eV) and low-lying lowest unoccupied molecular orbital (LUMO) energy level, ultra-low driving voltages can be expected by utilizing TCPZ as the host. TCPZ can be used for high performance deep-red, green and blue PhOLEDs for its good bipolar transport feature.

Ir(ppy)3:TCPZ has a lifetime about two times longer than that of the Ir(ppy)3 triplet excitons due to the triplet exciplex formed between Ir(ppy)3 and TCPZ.
