Abstract
Covalently organic derivatization of [Li<sup>+</sup>@C<sub>60</sub>]PF<sub>6</sub><sup>–</sup> to obtain Li<sup>+</sup>-encapsulated PCBM, [Li<sup>+</sup>@PCBM]PF<sub>6</sub><sup>–</sup>, is described. Synthetic procedures, electrochemical properties, light absorption properties, details of isomerization from [5,6]- to [6,6]-isomer, and X-ray crystal structure of [Li<sup>+</sup>@PCBM]PF<sub>6</sub><sup>–</sup> are discussed
