RESUMO
A DFT/TDDFT model was developed to predict the chemical properties for three colored to nearly transmissive electrochromic polymers synthesized by the John Reynolds's group. Using a functional-basis set pairing of mPW1PBE/cc-PVDZ along with the conductor polarizable calculation model (CPCM), simulated neutral spectra showed a strong correlation to the experimental UV-Vis data where the largest absolute peak maximum difference was 14 nm. Frontier molecular orbitals, electronic transitions, and ground-state geometries of these systems were evaluated to provide further information about the oxidative process the polymers undergo. Here we report the first colorimetric model using this level of theory.
