Graphene & Fullerenes
C60 fullerenes from 95% to 99.9%, PCBM for organic photovoltaics, and epitaxial graphene on silicon carbide substrates for electronics research.
Graphene and fullerenes are the two-dimensional and zero-dimensional forms of carbon, and each has found its niche in research and devices. This sub-category supplies Fullerene C60 at purities of 95%+, 98%+, 99%+, 99.5%+ and 99.9%+, the electron acceptor [6,6]-Phenyl C61 butyric acid methyl ester (PCBM) at 99.5% and double-layer epitaxial graphene on semi-insulating and n-type SiC substrates of 20 x 20 mm.
For fullerenes, purity determines electronic behaviour. Higher fullerenes and oxidised species act as traps in organic electronics, so device researchers favour 99.5% and above, while lower grades serve chemistry and cosmetic research. Graphene on SiC is grown epitaxially, so the substrate type and layer count are the key specification points for transport and device studies.
- C60 grades for chemistry, materials and devices
- PCBM for organic solar cells and transistors
- Epitaxial graphene on SiC for electronic measurements
Fullerenes ship in amber vials, and graphene substrates in clean wafer boxes. Each order includes a COA.
Graphene & Fullerenes: questions buyers ask
Why is PCBM used in organic solar cells?
PCBM is a soluble fullerene derivative that accepts electrons efficiently from conjugated polymers. Mixed with a donor polymer, it forms a bulk heterojunction where light creates charges that separate at the interface. It has been the standard acceptor for many years, though newer non-fullerene acceptors now compete with it.
How should fullerenes be stored?
Store C60 and PCBM in the dark, in sealed containers under inert gas if possible. Light and oxygen together can oxidise fullerenes, creating impurities that act as charge traps. For device work, keep solutions fresh and handle them in a glovebox to maintain performance.
What is epitaxial graphene on SiC?
Epitaxial graphene forms when silicon sublimes from a silicon carbide surface at high temperature, leaving carbon layers that arrange into graphene. It sits on a wafer-scale insulating or semiconducting substrate without transfer, which suits electronic and metrology studies. Layer count and substrate doping are specified for each sample.
