1,4,5,8,9,11-Hexaazatriphenylenehexacarbonitrile, also known as HAT-CN, 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.
It has been proven that using HAT-CN as a hole injection layer (HIL) material can dramatically enhance the performance of solution-processed organic light-emitting diodes . Lin et al further demonstrated that the external quantum efficiency, current efficiency, and power efficiency of the HAT-CN based devices were higher than or almost similar to those of optimised PEDOT:PSS-based devices. Solution-processed HAT-CN is promising as a novel alternative to conventional PEDOT:PSS HILs, due to its efficient carrier-injection capability and the capacity to prevent interfacial mixing and erosion during fabrication.
