Biography & Contributions

Harold Walter Kroto is an English chemist and Nobel laureate born on October 07, 1939. Kroto was the co-discoverer of buckminsterfullerene [C60]. He got many prizes and medals like International Prize for New Materials American Physical Society and as well as Italgas Prize for Innovation in Chemistry in the year of 1992, Royal Society of Chemistry Longstaff Medal in the year of 1993, Hewlett Packard Europhysics Prize in the year of 1994, Nobel Prize in Chemistry in the year of 1996, Dalton Medal in the year of 1998, Faraday Award and Lecture in the year of 2001, Erasmus Medal of Academia Europaea and Copley Medal of the Royal Society in the year of 2002.

Kroto had studied some unpublished research on carbon suboxide and this led to a general interest in molecules containing chains of carbon atoms with numerous multiple bonds.

He has also studied the electronic spectroscopy of free radicals, fullerene chemistry, multiple bond molecule design, molecular structures of carbon vapor and nanotubes, and also made phosphaalkenes compounds.

Kroto used microwave spectroscopy to discover long chainlike carbon molecules in the atmospheres of stars and gas clouds. In a series of experiments carried out conducted by Robert Curl and Richard Smalley and kroto, generated clusters of carbon atoms by vaporizing graphite in an atmosphere of helium. Some of the spectra they obtained from the vaporization corresponded to previously unknown forms of carbon containing even numbers of carbon atoms ranging from 40 to more than 100. Most of the new carbon molecules had a structure of C60. The researchers recognized that this molecule’s atoms are bonded together in a highly symmetrical hollow structure that resembles a sphere or ball. Kroto was the first person to coin the C60 carbon molecule as buckminsterfullerene.

Carbon Suboxide

Carbon suboxide is an oxide of carbon. Its four cumulative double bonds make it a cumulene. It is one of the stable members of the series of linear oxocarbons. Carbon suboxide is commonly described as an oily liquid or gas at room temperature with an extremely noxious odor. It is synthesized by warming a dry mixture of phosphorus pentoxide and malonic acid or the esters of malonic acid.

Carbon suboxide is used in the preparation of malonates and as an auxiliary to improve the dye affinity of furs. Carbon suboxide can be produced in small amounts in any biochemical process that normally produces carbon monoxide.

It can also be formed from malonic acid. Carbon suboxide has been shown that carbon suboxide in an organism can quickly polymerize into macrocyclic polycarbon structures.
