Introduction to Fullerenes
Fullerene is an allotrope of carbon. Any substance composed solely of carbon and existing in a spherical, elliptical, or tubular structure can be called a fullerene. Fullerenes are similar in structure to graphite, but while graphite's structure contains only six-membered rings, fullerenes may contain five-membered rings. In 1985, Robert Curl and others prepared C60. In 1989, experiments by German scientists Huffman and Kraetschmer confirmed the cage structure of C60, since then, the fullerenes discovered by physicists have been pushed by the scientific community into a new research stage. The structure of fullerenes is similar to the representative works of architect Fuller, hence the name fullerene.
As a prominent representative of the fullerene family, the C60 molecule is a spherical 32-hedron composed of 60 carbon atoms connected by 20 six-membered rings and 12 five-membered rings, which is very close to the structure of a football. Its unique structure and extraordinary properties have attracted the attention of scientists from all over the world. So far, research on C60 has involved numerous disciplines and applied research fields such as energy, lasers, superconductors and ferromagnets, life sciences, materials science, polymer science, and catalysis, and it is increasingly showing great potential and important research and application value.
Fullerenes and Their Applications
Due to their excellent properties (or functions) such as free radical scavenging, light absorption, superconductivity and semiconductivity, perfect structure, DNA affinity, electron accepting, high-efficiency adsorption, and endohedral molecules, fullerenes have been widely applied in many fields including daily cosmetics, pharmaceutical intermediates, health products, rubber/film material modifiers, high-new energy sources, and composite material additives.
