Buckminsterfullerene is the smallest fullerene molecule containing pentagonal and hexagonal rings in which no two pentagons share an edge (which can be destabilizing, as in pentalene). It is also the most common in terms of natural occurrence, as it can often be found in soot.
The structure of C60 is a truncated icosahedron, which resembles an association football ball of the type made of twenty hexagons and twelve pentagons, with a carbon atom at the vertices of each polygon and a bond along each polygon edge. The van der Waals diameter of a C60 molecule is about 1.1 nanometers (nm).[24] The nucleus to nucleus diameter of a C60 molecule is about 0.71 nm.
The C60 molecule has two bond lengths. The 6:6 ring bonds (between two hexagons) can be considered "double bonds" and are shorter than the 6:5 bonds (between a hexagon and a pentagon). Its average bond length is 1.4 angstroms.
Functions and applications of fullerenes and their derivatives
Due to its excellent radical scavenging, light absorption, superconducting semiconductors, perfect structure, DNA affinity, electron acceptor, efficient adsorption characteristics of embedded molecules (or functional), fullerenes and their derivatives have been widely applied in cosmetics , pharmaceutical intermediates, health products, rubber/film material modifiers , high energy , composite materials, additives, and other areas.
Shanghai Soyoung Biotechnology Inc. focus on manufacture and supply raw materials on nutritional ingredient, pharmaceutical Intermediate, cosmetics and related industries .
We has two manufacturing sites located in Shanxi and Fujian, as well as the stable and reliable supplying channel to cater the pharmaceutical and food industries globally. We are manufacturing strictly according to GMP requirement, besides the GMP approval of SFDA, some of products abtained FDA approval, COS certificate.

Preparation of C60.In 1989, German scientists Huffman and Kraetschmer experiments confirmed the cage structure of C60, physicists discovered fullerenes from now on by the scientific community to a new phase of research.Fullerenes are of a similar structure and the representative work of architect Fuller so called fullerenes.
Preliminary studies suggest that fullerene compounds in anti-hiv, DNA enzyme activity inhibition, cutting, kinetics of light therapy has a unique effect.
