(a) Diffraction pattern of the phase I crystals in 2D confinement extracted from the experimental results (Figs. 3[link] and 5[link]). (b) A schematic illustration of the cell orientation in the parent crystal (marked in orange) and the 45°-tilted crystals (purple). (c) The probable branching mechanism between the a1-axis-oriented and 45°-tilted crystals. The orange arrow represents the rod long axis. The helix A and two neighbouring helices B and C are marked in green in part (c). (d) The calculated diffraction pattern with the [001]-zone for the a1-axis-oriented crystals. (e) The calculated diffraction pattern for the 45°-tilted crystals; the [001]-zone diffraction pattern is rotated 45° clockwise in the ab plane around the c axis. (f) The diffraction pattern of the superposition of parts (d) and (e).
