Intermolecular hydrogen bonding in mixed mesomorphism

Exhibition of mixed mesophases in binary systems where both the components are non-mesogenic should offer a very interesting study because that should throw light on the mode of formation of mixed liquid crystal and factors f avourably affecting it or otherwise. Five binary systems of non-mesogenic c ompounds were investigated for the induction of thermotropic mesophases. In three binary systems induced nematic and smectic mesophases are observed i n number of compositions.
