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

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.

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.

Four grades are available.

Custom Mw and pdi available.

Fluoro-PTAA is also available.
