通过改进的电弧放电方法合成了全氟连接基团桥连的富勒烯二联体。在电弧放电反应器中加入聚四氟乙烯会导致形成由CF2基团桥接的两个C60富勒烯组成的二联体。含有电负性原子的桥联基团的掺入导致不同的能级和光致发光光谱中的新特征。单重态氧光敏化的抑制表明，从单重态到单重态的辐射衰减有利于对抗系统间交叉单重态到三重态的跃迁。
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.
