a) UV-vis spectra of poly-(S)-1 in THF, DCM and DMF and poly-(S)-2 in DMF. b ECD spectra of poly-(S)-1 in THF and DCM. c ECD spectra of poly-(S)-1 and poly-(S)-2 in DMF. d Schematic representation of the helical structure of PPA in a cis-cisoidal and a cis-transoidal conformation. [poly-(R)−1] = 0.6 mg/mL, [poly-(R)−2] = 0.6 mg/mL. (Abs, absorbance; ECD, electronic circular dichroism).
