Fullerene or C 60 is soccer-ball-shaped or I h with 12 pentagons and 20 hexagons. According to Euler's theorem these 12 pentagons are required for closure of the carbon network consisting of n hexagons and C 60 is the first stable fullerene because it is the smallest possible to obey this rule.
Nested closed fullerenes have been named bucky onions. Cylindrical fullerenes are also called carbon nanotubes or buckytubes. [1] The bulk solid form of pure or mixed fullerenes is called fullerite. [2] Fullerenes had been predicted for some time, but only after their accidental synthesis in 1985 were they detected in nature [3] [4] and outer ...
Polyfullerenes are currently in an early research phase and real-world applications or even industrial production solutions are yet to be found. The main reasons for this are the novelty of combining fullerene chemistry with polymer chemistry and the fact that fullerene can be currently synthesized on a scale of a few grams.
Carbon nanotubes, also called buckytubes, are cylindrical carbon molecules with novel properties that make them potentially useful in a wide variety of applications (e.g., nano-electronics, optics, materials applications, etc.). They exhibit extraordinary strength, unique electrical properties, and are efficient conductors of heat.
C 60 in solution C 60 in extra virgin olive oil showing the characteristic purple color of pristine C 60 solutions. The solubility of fullerenes is generally low. Carbon disulfide dissolves 8g/L of C60, and the best solvent (1-chloronaphthalene) dissolves 53 g/L. up Still, fullerenes are the only known allotrope of carbon that can be dissolved in common solvents at room temperature.
They can be grown by precipitation at an interface between two liquids. They are semiconductors and have potential uses in field-effect transistors, solar cells, chemical sensors, and photocatalysts. When doped with alkali metals, such as potassium, they become superconductors at 18 K (−255.2 °C; −427.3 °F). [2]
The mechanical properties of carbon nanotubes reveal them as one of the strongest materials in nature. Carbon nanotubes (CNTs) are long hollow cylinders of graphene . Although graphene sheets have 2D symmetry, carbon nanotubes by geometry have different properties in axial and radial directions.
C 70 fullerene is the fullerene molecule consisting of 70 carbon atoms. It is a cage-like fused-ring structure which resembles a rugby ball, made of 25 hexagons and 12 pentagons, with a carbon atom at the vertices of each polygon and a bond along each polygon edge.
