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.
Color code: green = Cl, blue = Ir, ochre = P. A transition metal fullerene complex is a coordination complex wherein fullerene serves as a ligand. Fullerenes are typically spheroidal carbon compounds, the most prevalent being buckminsterfullerene, C 60. [2]
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 ...
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 are called intrinsic polymeric fullerenes, or more often all C 60 polymers. Fullerene can be part of a polymer chain in many different ways. Fullerene-containing polymers are divided into following structural categories: Intrinsic polymeric fullerene (homopolymer), Main-chain polymers, Side-chain polymers, Star polymers, Crosslinked polymers,
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.
Besides unfilled fullerenes, endohedral metallofullerenes develop with different cage sizes like La@C 60 or La@C 82 and as different isomer cages. Aside from the dominant presence of mono-metal cages, numerous di-metal endohedral complexes and the tri-metal carbide fullerenes like Sc 3 C 2 @C 80 were also isolated. In 1999 a discovery drew ...
Heterofullerenes are classes of fullerenes, at least one carbon atom is replaced by another element. [ 1 ] [ 2 ] Based on spectroscopy , substitutions have been reported with boron ( borafullerenes ), [ 3 ] [ 4 ] nitrogen ( azafullerenes ), [ 5 ] [ 6 ] oxygen , [ 7 ] arsenic , germanium , [ 8 ] phosphorus , [ 9 ] silicon , [ 10 ] [ 11 ] iron ...
