STS Ltd. Company develops the leading technology for the commercial-scale manufacture of fullerenes and other fullerenic materials.

A fullerene is a molecule of carbon in the form of a hollow sphere, ellipsoid, tube, and many other shapes. Spherical fullerenes are also called Buckminsterfullerene (buckyballs), and they resemble the balls used in football.

Production technology

Fullerene production processes comprise the following five subprocesses: (I) synthesis of fullerenes or fullerene-containing soot; (II) extraction; (III) separation (purification) for each fullerene molecule, yielding pure fullerenes such as C60; (IV) synthesis of derivatives (mostly using the techniques of organic synthesis); (V) other post-processing such as dispersion into a matrix. The two synthesis methods used in practice are the arc method, and the combustion method.


Method of measurement

The step involves sublimation methods based on temperature gradients and solvent methods based on liquid chromatography. Fullerene purification means the separation of the different fullerenes in the fullerene extract into C60, C70. The main technique for fullerene purification is liquid chromatography (LC). LC is a wet chemistry method which includes a solution (called the mobile phase) of a molecular mixture. This solution is forced to pass through a column filled with a high surface area solid (called the stationary phase).
