1,4,5,8,9,11-Hexaazatriphenylenehexacarbonitrile, also known as HAT-CN (CAS number 105598-27-4), is one of the members of the 1,4,5,8,9,12-hexaazatriphenylene (HAT) family, which have an electron-deficient, rigid, planar, aromatic discotic system with an excellent π–π stacking ability. For this reason, HAT-CN finds applications in organic light-emitting diodes (OLEDs) serving either as the hole-injection layer (HIL) or charge-generation layer (CGL) material.
