Product Introduction
Fullerene C70 (CAS No. 115383-22-7) is a carbon allotrope consisting of 70 carbon atoms arranged in a closed-cage molecular structure. Compared with the spherical Fullerene C60, C70 features an elongated ellipsoidal carbon framework with extended π-conjugation, providing unique electronic, optical, and molecular properties.
Due to its strong electron-accepting ability, excellent charge transport characteristics, and nanoscale carbon structure, Fullerene C70 is widely used as a functional material in organic photovoltaics, perovskite solar cells, organic electronics, nanotechnology, and advanced energy materials research.
High-purity Fullerene C70 is particularly valuable in optoelectronic research where controlled electronic properties and efficient charge transfer are required.
