Face-to-face C6F5–[60]fullerene interaction for ordering fullerene molecules and application to thin-film organic photovoltaics

Abstract

Treatment of [60]fullerene with potassium methylnaphthalenide and excess C(6)F(5)CH(2)Br afforded 1,4-bis(pentafluorobenzyl)[60]fullerene, the study of which showed that there is a face-to-face interaction between [60]fullerene and a perfluoro aromatic ring, allowing the molecule to be utilized for high-performance organic photovoltaic devices.
