Figure 7

(A) Cyclic voltammograms (CVs) of 5.0 mM berberine cation (Ber+) and 10.0 mM EDOT in 0.10 M TBAPF6 solution between 0 and 2.0 V potential range, and (B) CV of the polymer in 0.10 TBAPF6 solution (neat background electrolyte without the monomers) between − 2.0 V–2.0 V potential range. (C) CVs of 10.0 mM PEDOT in 0.10 M TBAPF6 in acetonitrile solution between 0 V–2.0 V potential range. (D) CV of the polymer in 0.10 TBAPF6 acetonitrile solution between − 2.0 V–2.0 V potential range. (E) UV–Visible absorption spectra of Ber+-EDOT co-polymer and PEDOT. (F) Spectra in (E) in the range from 270 to 450 nm showing π \(\to \) π* and n \(\to \) π* transitions.
