4,4'-Cyclohexylidenebis[N,N-bis(4-methylphenyl)aniline] Chemical Properties,Uses,Production

Applications

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.

Description

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

Chemical Properties

Light yellow solid

Uses

This material is a popular Hole Transport Layer material for OLED devices.
