Descrizione generale

1-Pyrenebutyric acid (PBA) is a conjugated polymer that has a large π system and a carboxylic group. It is majorly used in surface functionalization. It has a high fluorescence efficiency and stability that make it useful in optoelectronic applications.

Applicazioni

PBA can be grafted on the surface of graphene and can be used in sensors. It can also be in the fabrication of ultracapacitor electrodes as alternative storage systems. It can also be used in the formation of multi-layered film for photovoltaic applications.

Cell-penetrating peptides (CPPs) are membrane permeable vectors recognized for their intrinsic ability to gain access to the cell interior. The hydrophobic counter-anion, pyrenebutyrate, enhances cellular uptake of oligoarginine CPPs. To elucidate CPP uptake mechanisms, the effect of pyrenebutyrate on well-recognized

A redox-labeled direct competitive electrochemical immunoassay for polycyclic aromatic hydrocarbons (PAHs) was developed. A ruthenium tris(bipyridine)-pyrenebutyric acid conjugate was synthesized as the redox-labeled tracer. Its recognition by an anti-PAH monoclonal antibody was confirmed by surface plasmon resonance. In the immunoassay

FRET-based fluorogenic substrates for lipases and esterases were prepared in four steps from commercially available building blocks. The substrates are pyrenebutyric acid monoesters of aliphatic 1,2-diols bearing a dinitrophenylamino group as a quencher. The most enzyme-reactive substrate is ester 2a.
