General description
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.
Insoluble small gap fullerenes can be extracted into organic solvents by simple chemical redox process.
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.
Application
Small gap fullerenes can be used as doping agents on polyaniline (PANI) for organic electronics applications.
