Fig. 1. (a) Synthesis of LPANI from polymer precursor P1, and the redox interconversion of its LLB, LEB, and LPB forms. (b) Size exclusion chromatogram, calculated Mn, and polydispersity (Đ) values. (c) UV-vis spectra of the oxidation process from LLB to LEB to LPB in THF; (inset) photographic images of LLB, LEB and LPB solutions. (d) Protonation of LPB with MSA and structural formulae of the closed-shell and open-shell resonance forms of the protonated LPS form.
