A new allotrope of carbon has been created that is being described as graphene’s ‘superatomic’ cousin by the team of US researchers behind it. Dubbed graphullerene, this atom-thin material is made of linked fullerene subunits. This novel form of carbon combines elements of two-dimensional carbon sheets and zero-dimensional carbon superatoms, and it could facilitate the development of new nanomaterials with applications in the electronics, aerospace, automotive and defence industries.

Carbon naturally exists in a range of allotropes such as diamond and graphite. The latest allotrope, graphullerene, is a two-dimensional polymer. A team of more than two dozen researchers at several US universities – including Columbia University and the University of Florida – created it using a chemical vapour transport strategy to first grow crystals of magnesium-doped fullerene polymers. Next, single sheets of graphullerene were exfoliated from the bulk material and a dilute acid was then used to remove the magnesium. Graphullerene’s specific combination of properties offers ‘a pristine interface that might find usefulness in new quantum materials applications’, said Austin Evans, a co-author of the paper and assistant chemistry professor at the University of Florida. As this material has proven to be very thermally conductive, it might be useful in thermal management for circuits or as protective coatings for spacecraft, he emphasised.ReferencesE Meirzadeh et al, Nature, 2023, DOI: 10.1038/s41586-022-05401-wRebecca TragerSenior US correspondent, Chemistry World Related articlesResearchGraphene-like structure created from a fullerene2022-06-30T13:30:00Z2D material synthesised from nanocluster fullerene for the first timeResearchLarge flakes of unusual 2D carbon allotrope made for the first time2022-05-25T13:58:00ZMove over graphene, say hello to graphyneResearchNew carbon allotrope predicted to hit bandgap sweet spot2020-09-30T14:21:00ZMixed hybridisations of carbon could see Me-graphene have a Poisson’s ratio close to zero More NewsBusinessExxonMobil scientists’ climate models were accurate, but hidden2023-01-12T19:02:00ZDocuments show internal predictions were as good as contemporary science but executives publicly downplayed their significanceBusinessSecond Alzheimer’s antibody approved in the US2023-01-12T15:40:00ZBiogen–Eisai’s lecanemab can slow disease progression a little, but at significant cost and risk of side effectsNewsInstitution of Chemical Engineers gets new chief executive2023-01-12T14:30:00ZYvonne Baker, a chemical engineer who heads Stem Learning, will assume the helm of the IChemE in April SubscribeAdvertise with the RSCTopicsIssuesContributors HelpContactPrivacyCookiesTerms of useAccessibilityPermissions Our mission News and events Campaigns Awards and funding Global challenges Support our work © Royal Society of Chemistry Registered charity number: 207890 This website collects cookies to deliver a better user experience.
