One-pot selective synthesis of a fullerene bisadduct for organic solar cell applications

Abstract

A single isomer of fullerene bisadduct, PC₆₁PF, was obtained from commercially available fullerene derivative, PC₆₁BM, in one pot over two steps. The tether-directed remote functionalization approach provided a very simple and fast method to produce a single isomer of fullerene bisadduct with good yield and easy purification. Bulk heterojunction organic solar cells containing the bisadduct was fabricated and tested.
