Abstract
The invention relates to hexa-substituted tribenzocyclononatriene derivats constituting a new type of liquid crystals with novel 'pyramidal' mesophases. The compounds of the invention differ from the known liquid crystals in their different steric molecular structure. Their molecules consist of a rigid central nucleus of pyramidal structure, the chains of substituents being symmetrically attached to the basis of the pyramid. The compounds of the invention have an electric dipole moment and can be excited in the electric field. Therefore, they are suitable for use in memory devices and/or electro-optical display means.
