The natural next step is to check whether we can optimize the parameters further to build modular polymer with larger mobility values. For this purpose, we begin with the parameter set corresponding to the highest mobility polymer found during the screening (polymer #36). Improvement of the reorganization energies of the constituting monomers from 𝜆 𝑘 = 0.11 eV to 0.08 eV (smallest of the parameter values obtained for the screened polymers) improves the mobility only by 0.5%. However, significant improvement in mobility is achieved by reducing the static disorder in electronic coupling which can be quantitatively defined by 𝜎 𝜏 /〈𝜏〉 where 〈𝜏〉 and 𝜎 𝜏 are the mean and standard deviation in HOMO-HOMO coupling respectively. Reducing 𝜎 𝜏 /〈𝜏〉 up to the realistic limit (0.03smallest value obtained for the screened polymers) we find that the charge-mobility can be enhanced almost 5-fold compared to that obtained for polymer #36 during our screening (Fig. ); the largest computed 〈𝜇〉, within the realistic range of key parameters, is ~30 cm 2 /Vs for 𝜏 (0) = 1.66 eV, 𝜎 𝜏 /〈𝜏〉 = 0.03, ∆𝜖 = 2.3 eV, and 𝜆 𝑘 = 0.08 eV with only 2 monomers in the structural repeating unit of the polymer (〈𝜇〉 scales trivially with the length of the structural repeating unit ). The shift of the mobility maxima with reduced 𝜎 𝜏 /〈𝜏〉 towards slightly larger 𝜏 (0) (Fig. ) indicates that with reduced disorder in the electronic coupling we approach more towards the band transport of the charge-carrier.
