A novel “double cable” material for photodiodes, containing both electron- and hole-transporting functional groups, is obtained by co-polymerization of thiophenes that bear a covalently linker-bound fullerene (see Figure). Even at 14 % of fullerene substitution, the order of the main polythiophene chain is not seriously disturbed.

Abstract
A novel “double cable” material for photodiodes, containing both electron- and hole-transporting functional groups, is obtained by co-polymerization of thiophenes that bear a covalently linker-bound fullerene (see Figure). Even at 14 % of fullerene substitution, the order of the main polythiophene chain is not seriously disturbed.
