mCPCN

mCPCN, 9-(3-(9H-Carbazol-9-yl)phenyl)-9H-carbazole-3-carbonitrile, is an asymmetric bipolar and high-triplet-energy (E_T = 3.03 eV) phosphorescent host material which could be used for hosting blue, green, red and white light emitting TADF-OLED devices.

The incorporation of the simple and small CN group can greatly improve film morphology and device thermal stabilities. Compared to mCP, CN group attached to the 3-position of the carbazole unit in mCPCN is believed to increases the electron affinity to achieve a rather balanced hole–electron injection and transport properties while not altering electronic transition energies and maintaining a high triplet energy.
