- triphenylbenzenes include 1,3,5-tris (4-N, N-diphenylaminophenyl) benzene (TDAPB) (4) W 200
- triphenylbenzenes form an amorphous film and have an oxidation potential in the range of 0.6 to 0.7 V.
- oxidation-reduction process is irreversible, they can be used as a practical organic semiconductor. Not suitable for use.
- triaminobenzenes include 1,3,5-tris (N-methylphenyl-1-N-phenylamino) benzene (6) (MTDAB)
- Such triaminobenzenes also have an oxidation potential of about 0.5 to 0.6 V.
- triphenylbenzenes all of them have an irreversible redox process. Glass transition temperature is about 60 ° C or lower. Therefore, it is not suitable for use as a practical organic semiconductor, and also has a problem in terms of heat resistance.
