AC-CNP, TADF yellow to orange dopant material

Available in sublimed grade for highly efficient TADF-OLED devices, 5,6-Bis(4-(9,9-dimethylacridin-10(9H)-yl)phenyl)pyrazine-2,3-dicarbonitrile, CAS No. 1883400-34-7

Ac-CNP, 5,6-bis(4-(9,9-dimethylacridin-10(9H)-yl)phenyl)pyrazine-2,3-dicarbonitrile is a TADF yellow to orange emitter with a simple structure of a low-rigid two cyano groups attached electron-accepting pyrazine unit and two electron-donating phenyl acridine units. The two phenyl units act as bridges to the donor acridines and acceptor pyrazine-2,3-dicarbonitrile to form a bipolar A-π-D electronic structure.

Ac-CNP has high photoluminescence quantum yield (PLQY) of 67% and Ac-CNP based devices with mCP as the TADF host showed a high external quantum efficiency (EQE) of 13.3%.
