Abstract

Fullerene dyads bridged with perfluorinated linking groups have been synthesized through a modified arc‐discharge procedure. The addition of Teflon inside an arc‐discharge reactor leads to the formation of dyads, consisting of two C60 fullerenes bridged by CF2 groups. The incorporation of bridging groups containing electronegative atoms lead to different energy levels and to new features in the photoluminescence spectrum. A suppression of the singlet oxygen photosensitization indicated that the radiative decay from singlet‐to‐singlet state is favoured against the intersystem crossing singlet‐to‐triplet transition.
