Description

Fullerene-C70, Purity: 99.5% – Ultra-High Purity Nanocarbon for Advanced Functional Materials

Fullerene-C70 (C₇₀) is a molecular carbon allotrope composed of 70 carbon atoms arranged in a closed-cage, ellipsoidal structure made of 25 hexagons and 12 pentagons—forming a shape similar to a rugby ball. Each carbon atom occupies the vertex of a polygon, with bonds along the edges, creating a delocalized π-electron system that enables excellent thermal stability, chemical reactivity, and electrical conductivity.

With a purity of 99.5%, this grade of Fullerene-C70 is ideal for high-end applications where ultra-low impurity levels are essential. It is synthesized from high-grade graphite using arc-discharge and vacuum sublimation techniques and is thoroughly purified to eliminate residual catalysts, amorphous carbon, and higher fullerenes.

Compared to C60, Fullerene-C70 exhibits lower symmetry but greater surface reactivity and selectivity in chemical functionalization, making it highly valuable in the fields of energy storage, pharmaceuticals, electronics, and nanotechnology. It also plays a critical role in developing and studying higher-order fullerenes (e.g., C76, C78, C84) and chiral carbon structures with advanced optoelectronic properties.

Mechanical studies such as nanoindentation have shown that Fullerene-C70 possesses rigidity over 200 times higher than amorphous carbon, and retains structural integrity under high stress. Its solubility in organic solvents like toluene and CS₂ makes it convenient for both solution processing and thin-film fabrication.
