(a) Optical texture of compound 1a at T=110 °C (crossed polarizers). (b) Same texture, but with λ-retarder plate (the indicatrix orientation in the compensator is shown on the right). (c) SAXS pattern of the p4gm phase of 1a at 100 °C; the inset is the θ-scan of the diffraction pattern of 1a in the wide-angle region, recorded with CuKα radiation. (d) GISAXS pattern of the p4gm phase of 1b at 100 °C; superimposed are reciprocal lattices for two of the observed orientations, with (10) and (21) planes in contact with the substrate, respectively (([macr2]1) orientation with dashed lines); pattern showing (11) orientation is shown in Supplementary Fig. S8.
