General description

6-Phosphonohexanoic acid (PHA) is an alkylphosphonic acid that forms a self-assembled monolayer (SAM) on a variety of surfaces. It has carboxylic groups that facilitate the grafting of the surface atoms while the phosphonic groups allow the surface modification of the substrate material.


PHA can be used in the surface functionalization of phynox material which can further be utilized in the biomedical applications such as surgical implant and stents. It can also be used in dispersing manganese dioxide (MnO2)-MWCNT for the formation of electrodes for supercapacitors. It may also be coated on indium tin oxide (ITO) as an alternative to silane based SAMs for the fabrication of organic electronic devices such as organic solar cells (OSCs).

There is widespread demand for thin, lightweight, and flexible electronic devices such as displays, sensors, actuators, and radio-frequency identification tags (RFIDs). Flexibility is necessary for scalability, portability, and mechanical robustness.

Recent research highlights tunable properties of inorganic nanoparticles, driving interest in optoelectronics.

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold).
