General description

Insoluble small gap fullerenes can be extracted into organic solvents by simple chemical redox process.

Small gap fullerenes are higher order fullerenes with low HOMO − LUMO gaps. These allotropes of carbon are also known as metallofullerenes. They are kinetically unstable and are considered as insoluble small band gap structures. They can be extracted into organic solvents by chemical redox processes.

Small gap fullerenes, also known as giant fullerenes, possess small energy differences between the valence band and the conduction band or between the filled and unfilled energy states of individual fullerene molecules.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.


Small gap fullerenes can be used as doping agents on polyaniline (PANI) for organic electronics applications.

Fullerenes for Bioscience & Photovoltaic Applications

Twenty-five years ago, it was discovered that carbon vapor preferentially condenses into an exceedingly stable cluster with 60 carbon atoms (C60), and it was hypothesized that the 60 atoms were arran...
