Description

General description

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.

Application

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.

Packaging

5 g in poly bottle

1 g in glass bottle
