Terthiophene-fullerene dyads

Terthiophene- fullerene dyad 2.106 (Chart 1.21), in which the fullerene unit was attached to the -position of the central thiophene unit through a rigid ethynyl spacer, was prepared by Komatsu et al. [207]. The synthesis was accomplished by lithiation of 3 -ethynylterthiophene [208] to generate the lithium acetylide, which subsequently was reacted with Ceo to form the ethynylated fullerenyl anion. By treatment of the latter with methyl iodide, dyad 2.106 was obtained in 35% yield. Another terthiophene-fullerene dyad...
