APPLICATIONS
|
Fullerene is a large molecule composed of carbon entirely. The general formula
is Cn, where n is even number from 32. Their shapes are roughly spherical
similar to graphite with a surface net of carbon atoms connected in hexagonal
and pentagonal rings. The most common one is C60(also
known as "buckyball"). Fullerene is formed when vaporized and condensed carbon
are combined in an inert gas. They have very high thermal and oxidative
stability. They don't break but just separate from the solid intact. They are
fairly insoluble in many solvents. The properties and applications are
under research for the fields include;
- Diamond mimics
- Catalysts
- Cosmetics
- Superconductors
- Abrasive agent for cutting and grinding
applications.
- Dyes and Pigments
- Electrodes
- Lubricant additive
- Antioxidant for medicinal uses
- Antibiotics to target
bacteria
- Anticancer to certain cells
- Photoactive polymers
Recently DBU (1,8-diazabicyclo[5.4.0]undec-7-ene)
is used in fullerene purification in a
form of mixture with
trimethylbenzene. DBU reacts to C70 and higher fullerenes but not to C60
fullerenes.
