Improved Production and Separation Processes for Gadolinium Metallofullerenes

摘要: A comprehensive scheme for processing all arc-produced gadolinium monometallofullerenes into separate quantified fractions is presented. As generated by the carbon arc process, endohedral metallofullerenes are entrained in a complex mixture of more abundant empty fullerenes and carbonaceous soot. The process described herein exploits differences solubility redox reactivity between different classes Gd@C2n to effect their separation from one another. Importantly, processes not only facilitate use normally soluble metallofullerenes, such as Gd@C82, but also provide access insoluble Gd@C60. In quantifying contents obtained fractions, found be about 10% minority total metallofullerene product, while comprise up much 90% amount Gd@C2n. Thus, new class Gd@...
