PTAA, HTL material used to improve charge extraction in OLED/OFET devices

High quality polymer available with free shipping on qualifying orders


Methyl or fluoro substituted poly(triarylamines) (PTAAs) are electron rich with diphenylamine as the the backbone and substituted phenyl as side chains. Substituted PTAAs are originally used as hole transport layer (HTL) materials in OLED/OFET devices to improve charge extractions. PTAA can also act as electron blocking layer to reduce the chances of electron–hole recombination and energy loss in electronic devices. Fluorinated PTAA, 1F-PTAA and 2F-PTAA, can effectively downshift the HOMO levels of PTAA derivatives due to the electron deficiency of fluorine, resulting in an increase of VOC hence the power conversion efficiency (PCE) of the device.

PTAA from Ossila used in high impact paper

PTAA from Ossila was used in the high-impact paper (IF 30.85), Multiply Charged Conjugated Polyelectrolytes as a Multifunctional Interlayer for Efficient and Scalable Perovskite Solar Cells, E. Jung et al., Adv. Mater., 2002333 (2020); DOI: 10.1002/adma.202002333.

A range of substituted poly(triarylamine)'s (PTAA's) for use with small molecules for solution-processed high-mobility films. While PTAA has a relatively modest mobility on its own, it has been gaining interest when used in conjunction with small molecules to provide the combination of good coating parameters and high mobility [1,2].

Note: We also have a PTAA family member (PTAA for perovskites) for perovskite solar cell applications.
