Extended Data Fig. 10: Variations of the Raman peaks and widths of the out-of-plane C−H modes at different ethynylene-like bonds for 3a-EBPP and 5a-EBPP.

a,b, Plots of the measured Raman peaks and widths of the out-of-plane C−H modes at different ethynylene-like bonds for 3a-EBPP, and c,d, for 5a-EBPP, respectively. For 3a-EBPP and 5a-EBPP, the data are extracted from Fig. 3g and Supplementary Fig. 15f, respectively. The averaged spectra for C−H modes, acquired at sites near each ethynylene-like bond between neighbor pentacene moieties, are fitted separately by the Lorentzian function, shown as two sets of data for C−H modes close to each ethynylene-like site. The two data sets are plotted for the C−H modes obtained at the positions with respect to the polymer backbones, that is, positions 3 (a,c) and 7 (b,d) as labelled in Supplementary Fig. 15c,d. Error bars for the peak positions in Raman shift and for the peak width in FWHM are the standard errors obtained from the Lorentzian fitting of the Raman peaks, with centre of the error bar corresponding to the fitted peak position in each case. Spatial distributions of polaron densities |ψ|², same as those in Fig. 5 in the main text, are overlaid for comparison.
