Owing to their wide range of industrial utility and also as the most reliable method of identification, binary systems of liquid crystals have been a topic of extensive studies. The starting point of this article is the formation of charge-transfer complexes in the liquid crystalline state; therefore, the scope is limited to the enhancement of thermal stability of liquid crystals in such systems. The component compounds are not necessarily mesogenic. Various para-disubstituted benzenes can be employed as one of the components. Finally, emphasis is laid on the liquid crystals produced by mixing of nonmesogenic electron donor and acceptor. The effects of branching of alkyl group on the induction of liquid crystals are also described.
