PCA can be used in the surface modification of graphene and carbon nanotubes (CNTs), which can further be used for a variety of electronic applications.

1-Pyrenecarboxylic acid (PCA) is a polyaromatic derivative that has an amphiphilic characteristic. It is a fluorophore that shows absorption spectra in the UV region. PCA has a carboxylic acid group that attaches with pyrene nucleus. It can be used as a sensitizer that facilitates the electron transport from one medium to another.

Crystallise the acid from *C6H6, chlorobenzene, nitrobenzene or 95% EtOH. [Beilstein 9 H 712, 9 III 3575.]
