    • We used the Teter-Pade parametrization of the LDA functional, which reproduces the Ceperley-Alder data. The pseudopotentials were generated with the Trouiller-Martins scheme. Numerical convergence tests on the total energy with a requirement of a precision of 1 mhartree/atom was reached for a number of plane waves in the basis set corresponding to an energy cutoff of 35 hartree and a sampling of the Brillouin zone using 8 k -points in the case of semiconducting polymers and uto 20 k -points in the case of metallic polymers.

    • We used the 6-311 G** basis set for all calculations if not otherwise stated. A difference of 0.1 eV on the singlet and triplet states of tetrathiophene (n=2 in Fig.) is calculated using the 6-311+ G** compared to 6-311 G**. Polymer Brillouin zones were sampled with over 100 k -points.
