Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine is one of the family members of poly(triaryl)amine.

Polymer for optoelectronic applications.

PTAA can be coated as a substrate material used for hole transport in the manufacture of many devices such as perovskite solar cells, organic light-emitting diodes (OLED) and organic field-effect transistors.

PTAA – SOL2426

CAS: 1333317-99-9

Excellent semiconductor material that transports holes and blocks electrons due to its electron-rich components.

The use of this polymer can significantly improve the open-circuit voltage (VOC) and the fill factor (FF) of the cells.

Hole transport material for organic light-emitting diodes (OLEDs) and perovskites. Amorphous p-type polymer semiconductor. Custom Mw and pdi available.

Fluoro-PTAA is also available.

Custom Mw and pdi available.

Choose between:

Low Mw: 5 – 20 kDa (SOL2426L)

Medium Mw: 20 – 75 kDa (SOL2426M)

High Mw: 75 – 200 kDa (SOL2426H)

Ultra-High Mw: 200 – 500 kDa (SOL2426UH)
