Covalently Chemical Modification of Lithium Ion-Encapsulated Fullerene: Synthesis and Characterization of [Li⁺@PCBM]PF₆^–

Abstract

Covalently organic derivatization of [Li⁺@C₆₀]PF₆^– to obtain Li⁺-encapsulated PCBM, [Li⁺@PCBM]PF₆^–, 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⁺@PCBM]PF₆^– are discussed
