Figure and S2 show two ways to analyse the effect of the sorbitol concentration on the conformers of PEDOT in amorphous morphologies. In Figure , we show that increased sorbitol content leads to an increase in planarity of the PEDOT molecules, with agrees with the improved stacking of PEDOT oligomers reported in the main body of the paper. Figure shows that the RMSD distribution between PEDOT oligomers and a fully elongated PEDOT conformer shows more distinct maxima in case of high sorbitol concentration. The first two maxima correspond to almost planar PEDOT conformers with zero and one monomer unit twisted around approximately 180°.
