About Carbon Nanohoops

Carbon Nanohoops are another name for [12]Cycloparaphenylene, an organic ring (nanoring) of para-benzene molecules. Researchers have also synthesized carbon nanohoops out of [9], [12], and [18]Cycloparaphenylenes, which may become comercially available in the future. The unique structure of carbon nanohoops allows them to be stacked on top of each other, serving as fundamental building blocks of single-walled carbon nanotubes. American Elements also manufactures numerous other carbon-based nanomaterials such as fullerenes, carbon nanorods, and graphene. See our Carbon Information Center for the full product line of American Elements carbon materials and our Nanomaterials Information Center for our nanoscale products from other elements and compounds. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available, as is additional technical and safety (MSDS) data. Please contact us for information on lead time and pricing above.

Carbon Bohr ModelThe number of electrons in each of Carbon's shells is 2, 4 and its electron configuration is [He]2s2 2p2. In its elemental form, carbon can take various physical forms (known as allotropes) based on the type of bonds between carbon atoms; the most well known allotropes are diamond, graphite, amorphous carbon, glassy carbon, and nanostructured forms such as carbon nanotubes, fullerenes, and nanofibers . Carbon is at the same time one of the softest (as graphite) and hardest (as diamond) materials found in nature. It is the 15th most abundant element in the Earth's crust, and the fourth most abundant element (by mass) in the universe after hydrogen, helium, and oxygen. Carbon was discovered by the Egyptians and Sumerians circa 3750 BC. It was first recognized as an element by Antoine Lavoisier in 1789.
