Abstract

Synthesis of Ar@C60 is described, using a route in which high-pressure argon filling of an open-fullerene and photochemical desulfinylation are the key steps for >95% encapsulation of the noble gas. Enrichment by recycling HPLC leads to quantitative incorporation of argon in the product endofullerene, with a mass recovery of tens of milligrams, allowing the first characterisation of fine structure in the solution 13C NMR spectrum.

Synthesis of Ar@C60 is described, using a route in which highpressure argon filling of an open-fullerene and photochemical desulfinylation are the key steps for 495% encapsulation of the noble gas
Enrichment by recycling HPLC leads to quantitative incorporation of argon in the product endofullerene, with a mass recovery of tens of milligrams, allowing the first characterisation of fine structure in the solution 13C NMR spectrum
Subsequent removal of empty C60 using preparative, recycling HPLC leads to enrichment of the sample.[6,9]
