1,1-Bis[(di-4-tolylamino)phenyl]cyclohexane, known as TAPC, has been widely used as a hole transport material in organic light-emitting diodes (OLEDs) due to its high hole mobility.

Having a higher ET (2.87 eV) than the typical blue phosphorescent guest material, TAPC can be used as both hole-transport layer material and as host for blue phosphorescent (such as FIrpic) guest molecules, resulting in a reduction of the number of organic layers and simplified OLED structures.
