Time-dependent powder XRD spectra of (a) CM1-s and (b) CM2-s under continuous X-ray exposure (λ = 1.54 Å). The numbers 1, 2, 3, 4 and 5 correspond to cumulative X-ray irradiation durations of 2, 4, 6, 8 and 10 hours, respectively. DSC studies of (c) CM1-s and (d) CM2-s at a heating rate of 10 °C/min. e False-color 2D GIWAXS plot of CM1-s during heating to 80 °C. f Corresponding 1D XRD patterns of CM1-s. g False-color 2D GIWAXS plot of CM2-s during heating to 80 °C. h Corresponding 1D XRD patterns of CM2-s. i, Cryo-EM image of polycrystalline CP1-s at low magnification. j, k High-resolution cryo-EM image and corresponding FFT of polycrystalline CP1-s at [001] axis orientation, showing the inter-chain separation of 1.35 nm and main-chain periodicity of 1.32 nm. The single-crystal model was superimposed on the image with a unit cell indicated by red dash line.
