FIG. 1.

Evolution of SAXS profiles to DG phase as a function of concentration (a) from L phase to DG phase and (b) from H phase to DG phase. For convenience, each profile is shifted along the intensity axis. The inset figure in (b) is an enlarged profile observed at to show the embedded peak at .

FIG. 2.

Change of 2D scattering patterns from LSFM-L to R structures. (a) and (b) patterns for LSFM-L structure and the corresponding (c) and (d) patterns for the R structure.

FIG. 3.

Schematic representations of the (a) LSFM-L structure and the (b) intermediate structure having the space group.

FIG. 4.

Fourier transform function of the circular averaged scattering function of LSFM-L pattern [Fig. 2(a)].

FIG. 5.

Reciprocal lattice of the structure having the space group. (a) Reflections from {0 1 1}, {0 1 2}, {0 0 3}, and families in a 3D presentation; (b) a scattering plane corresponds to the pattern, and (c) a scattering plane corresponds to the pattern. Reciprocal lattice points surrounded by circles in (b) and (c) meet the corresponding scattering planes.

FIG. 6.

Change of 2D scattering patterns in the to H transition, where the definitions of and are the same as in Fig. 2. In the geometry, (a) phase, (b) coexistence of and H phases and (c) H phase, and the corresponding schematic representations of the patterns with indexation are shown in (A), (B), and (C), respectively. In the geometry, (d) phase, (e) coexistence of and H phase and (f) H phase, and the corresponding schematic representations of the patterns with indexation are shown in (D), (E), and (F), respectively.

Schematic representation for to H phase transition model. The arrows indicate the direction of movement.

Image of FIG. 8.
FIG. 8.

Basic process of HPL to DG transition. The transition proceeds by rotation of the dihedral angle of connected tripods from planar state to 70.53°.

FIG. 9.

Geometrical relationship between HPL structure and G structure. (a) Single-network G structure generated from a HPL plane and (b) DG network structure generated from structure.

FIG. 10.

Two examples of evolutions of the patterns (series A; a1–a4 and series B; b1–b4) in LSFM-L to DG transition and the corresponding schematic representations of the patterns with the indexation (series A; A1–A4 and series B; B1–B4).
