I will discuss the discovery of buckminsterfullerene and the subsequent work in this area; I will do this in response to the supplied articles. With the discovery of buckminsterfullerene there are crucial stages which led on to further discovery. British chemist Harold Kroto had a great interested in molecules found in interstellar space and he "wanted to show that molecules containing long chains of carbon atoms". New apparatus were being developed which allowed the conditions of space to be reproduced. With graphite as a source of carbon, experimentation began with a high powered laser. These experiments were successful, these long chain molecules were found to be formed in the apparatus. Looking at the results the scientists noticed unusual patterns. A molecule with a mass spectrum, showing it consisted of exactly 60 carbon atom was formed "and appeared to be surprisingly stable". Under the right conditions C60 dominated the mass spectrum. ...read more.


The red colouring was unbelievable to the scientists, C60 was the only explanation. It's 13C nuclear magnetic resonance spectrum was almost incontrovertible proof of the structure, the ultimate "one-line" proof. "In the highly symmetrical structure of buckminsterfullerene, all the carbon atoms have exactly the same environment there is only one type of carbon atom." This "one-line" evidence was obtained in September 1990 and "dramatic further evidence for the whole family of closed caged molecules - the Fullerenes - was obtained from chemists work on C70. Finally a scientist in San Francisco had obtained a picture of C60 with gold atoms using the technique of scanning tunneling microscopy. Buckminsterfullerene consisted of exactly 60 carbon atoms and has the structure of a modern football. The ultra violet absorption of C60 is unusual, on a graph it is a hump in a negative correlation, It is soluble in certain solvents forming coloured solution. ...read more.


C60 superconductor properties would allow the use with in electronics, which would be good as with a superconductor no heat is produced so no cooling needed. Meaning smaller and more compact items can be produced. Buckminsterfullerene's discovery relied on just the curiosity of a scientist, yet its discovery was a blessing as so much can be done with it. The possibilities for its use seem endless, so within the scientific world it discovery is of great significance and excitement. Its use in the medical world t fight cancer, must be almost revolutionary. C60 discovery was a long and drawn out journey but all the work and years that the physicists and chemist put into it seem to be paying off. The discovery of buckminsterfullerene virtually revolutionised the ways in which scientist thought about carbon. First discovered in 1985 by British and American scientists, C60 and other fullerenes have bought versatility and potential of carbon forward. C60 properties are now being exploited and used in new treatment of cancer, and electronics. Elizabeth Morden 12DR 1 Candidate No. 7269 ...read more.
