Liquid crystalline behavior of polymeric materials is of considerable current interest in the
last decades, but due to many different and distinct characteristics. Polyazomethines liquid
crystalline polymers have received considerable attention due to their potential applications
and considered as one of the most important liquid crystalline material produced. This
review gives a simple introduction to liquid crystalline materials including definition and
classification. Moreover, we will focus on the syntheses and properties of liquid crystalline
polyazomethines with flexible spacers or hybrid liquid crystalline polyazomethines. Furthermore,
give a general overview of thermotropic, mesophoric properties and texture observation
for desired liquid crystalline polyazomethines were shown in details.

2,6-Diamino-4,8-dioxo-1,4,5,8-tetrahydropyrrolo[2,3-f]indole-3,7-dicarbonitrile derivatives (5a-g) were prepared by treatment of chloranil with two equivalents of malononitrile in presence of a basic catalyst given dimalononitrile derivative 3, and the latter reacts with two equivalents of a series of primary aromatic or aliphatic amines bearing different substituents in the para position. The resulting compounds were characterized by elemental and spectral analyses. In addition, the biological screening of selected samples was tested.
