Table 1 Supramolecular lattice analysis of the giant tetrahedra with different symmetry.

Lattice I structures were formed by slow evaporation of the sample solutions in THF/MeCN mixed solvents at 25°C; lattice II structures were formed after annealing treatment. dI is the determined periodicity of the lamellar structures.
