Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>We show that electron transfer from the perchlorotriphenylmethide anion (PTM⁻) to Y@C₈₂(<italic>C</italic>_{2<italic>v</italic>}) is an instantaneous process, suggesting potential applications for using PTM⁻ to perform redox titrations of numerous endohedral metallofullerenes. The first representative of a Y@C₈₂‐based salt containing the complex cation was prepared by treating Y@C₈₂(<italic>C</italic>_{2<italic>v</italic>}) with the [K⁺([18]crown‐6)]PTM⁻ salt. The synthesis developed involves the use of the [K⁺([18]crown‐6)]PTM⁻ salt as a provider of both a complex cation and an electron‐donating anion that is able to reduce Y@C₈₂(<italic>C</italic>_{2<italic>v</italic>}). For the first time, the molar absorption coefficients for neutral and anionic forms of the pure isomer of Y@C₈₂(<italic>C</italic>_{2<italic>v</italic>}) were determined in organic solvents with significantly different polarities.</p> </abstract>
