Abstract

The process according to the invention is a process for the production of aligned, ferroelectrically or ferrielectrically or antiferroelectrically ordered materials which solidify in a glass-like manner. In these layer structures with polar order, the molecular dipole moments are uncompensated, partially compensated or fully compensated, so that a dipole moment corresponding to the degree of compensation, acts externally.
