Synthesis and characterization of HAT-TP polymer, and theoretical guidance. (a) Typical synthesis route of HAT-TP and digital photograph of the as-prepared HAT-TP powder. (b) XRD patterns of HAT-TP polymer, HAT-CN monomer, and THA-NH2 monomer. (c) FT-IR spectra of HAT-TP polymer, as well as HAT-CN and THA-NH2 monomers. (d) 13C SS NMR spectrum of HAT-TP. (e) SEM image of HAT-TP powder, showing block shape. (f) TEM images of HAT-TP, as well as corresponding EDS elemental mapping with respect to C and N. (g) ESP distribution of HAT-TP and HAT-CN molecules, with red and blue respectively representing the electron-rich and electron-deficient regions within a molecule. (h) Calculation of the relative HOMO/LUMO energies and optimized structures of the HAT-TP and HAT-CN molecules, for use in DFT calculations.
