Fullarene DiscoveryDiscovered by smelly, Kroto, curl and coworkers in 1985,
they were awarded noble price in chemistry for their fullerene discovery in 1996.
fullerene familiarly named BuckminsterFuller

A New Form of CarbonDiamond Graphite C60 Buckyball
-
Fullerene synthesis KrtSchmer Huffman method, Arc Vaporization of graphite
-
Fullerene synthesisother methodlaser Ablation hydrocarbon combustion Indicatively RF evaporation of graphite and low pressure helium sputtering
-
Fullerene solubility C60 and C70 are sparingly soluble in many solvent but benzene, Toluene is familiar solvent used as reaction medium

Other structure Nanotubes
-
C60 structure C60 has a spherical structure like football with 7 diameter with 60 vertices and 32 faces the atoms connected in 5- and 6- membered ring (12-pentagonal, 20-hexagonal)
-
Fullerene ReactionsPossible reactions C60 and C70 (to a lesser extent) may undergoAdditionsPolymerizationSubstitutionsT
-
Fullerene reaction siteExohedral FullerenesAtoms, molecules, and complexes are attached to the exterior of the cage Endohedral FullerenesMolecules are enclosed within the cage
-
Endohedral FullerenesFullerene cages with encapsulated molecule have many potential applications. For example they will be able to encage a radioactive tracer and inject that safely into the human body.).
-
Endohedral FullerenesThe lanthanide metal fullerene are less research work but Gd3N@C80 are promising MRI agent which is give a high relaxtivity than common Gd-DoTA MRI agent actually used
-
Exohedral Fullerenes1: bonded to metal directly above C- atom with 6- bound.2: bounded to metal may (6, 6) or (6, 5), but (6, 6) is common.3: bounded to metal with 3- metal whether in 5-ring like allyl linkage.4: bounded metal to four atoms like butadiene .5: metal linked above a 5-memmber ring like cyclo-pentadienyl ligand.6: metal linked above a 6- member ring link benzene ligand
