Unexpected dimerization of oxidized fullerene-oligothiophene- fullerene triads
Autor: Bmw Bea Langeveld-Voss, Joop Knol, Raj René Janssen, Jj Joke Apperloo, Jc Jan Hummelen
Publikováno v: Advanced materials, 12(12), 908-911. WILEY-V C H VERLAG GMBH
Can bulky fullerene substituents reduce the dimerization tendency of oligothiophene radical cations? These authors prepared the dumbbell-shaped bis-C60-substituted oligothiophene shown in the Figure in order to address this question. Contrary to expe
