Please do not adjust margins Please do not adjust margins estimate the infinite polymer HOMO, LUMO and Eg energies. When utilizing the simple 1/n extrapolation method to determine the Eg energy of a polymer from its constituent oligomers, the predicted infinite polymer gap energy tends to underestimate the experimental energy due to the saturation effects of the π conjugated system . These saturation effects were neglected to simplify the analysis. The 1/n model was employed to the polymer HOMO, LUMO, and Eg energies for the 70 compounds in the octamer data set, and these values were used as the basis for the predictive models developed below.
