Fullerene Has Good Superconductivity and Luminescent Properties
Because the
characteristics of C60 crystal structure, it exhibits promise more special
physical properties .C60 is a black powder. Close degree of 1.650 ± 0.05g/ cm3, a melting point of greater than700 ℃.
It has an even number of carbon atoms, symmetry good, stable structure, easy to
dissolved in CS2, benzene, toluene, alkanes, and other non-polar organic solvent;
in aliphatic hydrocarbons, C60 carbon solubility with solvent increasing the
number of atoms increases.
Fullerene solubility:
Fullerene solubility in
aliphatic hydrocarbons with solvent molecules Number increases, but generally
less soluble. In Benzene and toluene has good solubility, in carbon disulfide
solubility is
great. However, due to
the high toxicity of carbon dioxide, it is generally not use. C60 is currently
the most commonly used for dissolving solvent is toluene.
Fullerene
Superconductivity;
C60 is a molecular
crystal at room temperature, spectrum calculations show that the face-centered
cubic solid C60 is able to 1.5eV bandgap semiconductors. After a suitable metal
doping, exhibit good superconductivity.
Fullerene luminescent
properties:
In a vacuum, C60 don’t
have the luminescent properties. When C60 crystal adsorbed some gas, or some
kind of crystal doped to C60 ingredients, even some of the groups on the
grafted C60 cage or organic molecules midnight, so the original can not emit
light with a luminescent molecule C60
quality.
