Molecular design of thermotropic liquid crystalline polyhydroxy amphiphiles exhibiting columnar and cubic mesophases of the normal type

The phase sequence Col(h1)-Cub(V1)-S-A-Col(h2)-Cub(12), which represents a major part of the theoretical lyotropic phase diagram of detergent solvent systems, was realized for the first time in a binary mixture of two thermotropic amphiphilic liquid crystals without any solvent.
