ABSTRACT:
Novel thermotropic liquid crystal complexes are produced by hydrogen bonding, essentially along the long axes, of two different thermotropic mesogenic compounds. The resultant new mesogenic complexes so produced exhibit mesogenic behavior not only over an expanded temperature range than both of the parent compounds, but also at a higher temperature than for either compound individually. This invention is applicable to both nematic and smectic mesogens.
