In order to estimate the persistence length of our PII-2T polymer, we first calculate the dihedral potentials within the repeat unit using density functional theory (DFT) with global hybrid function B3LYP in conjunction with a 6-31G(d,p) basis set using Gaussian 16. The side chains were substituted with CH3 to reduce computational cost. Using the method demonstrated by Milner and Gomez et al. , the dihedral potentials are then used to randomly generate a set of 500,000 polymer conformations (each with 20 repeat units) by rotating each rotatable segment in accordance with a Boltzmann distribution using the dihedral potential. A breakdown of the PII-2T repeat unit along with the segment lengths and deflection angles are shown in Figure and Table . The persistence length is then extracted from the decay of the average tangent-tangent correlation function
