Fig. 6

X-ray scattering profiles of PAImXY(#) and X-ray crystal structure of 12. X-ray scattering profiles of PAImXY(#)(I-) in vacuo (a, b) and hydrated (c, d). Figures in the left hand column (a, c) are plotted on a log–log scale to show overall structure. Figures in the middle column (b, d) are plotted lin–lin to focus on the wide-angle scattering (smaller structure). The curves are vertically offset for clarity. e X-ray crystal structure of model compound 12 in its iodide form (ellipsoid set at 50% probability) with distance of iodide to C2 represented by a line. f The size of the correlated regions observed in the hydrated samples with different side chains obtained by fitting Equation 6 to the SAXS data
