  1. Peak temperatures from the first DCS heating (H) and cooling (C) cycles at 10 K min−1 (DSCs of the second scans, see Supplementary Fig. 1), enthalpy values (ΔH/kJ mol−1) are given in square brackets after the phase-transition temperatures.
  2. a Lattice parameter, ncell number of molecules per unit cell (for calculations and further details, see Supplementary Tables 7–11 in the Supplementary Methods 4.3); Cr cystalline solid, Iso isotropic liquid, Cub cubic LC phase; ColhexΔ triangular honeycomb LC phase; ColhexΔ/□ Colhex phase with hexagonal superlattice formed by dodecagonal supertiles (the subscripts Δ and Δ/□ indicate the shape of the prismatic cells forming the tiling pattern of the distinct Colhex phases); ColsquT square honeycomb with tilted molecules.
