“…Strong demand of new LCs for applications has led to the synthesis of wide range of mesogens, in particular, thermotropic liquid crystals [4,5]. Most thermotropic liquid crystals belonged to the calamitic molecules which have a rigid core that consisted of two or more phenyl rings and one or more flexible terminal alkyl chains.…”

Two new compounds, 4-alkanoyloxybenzylidene-4 -fluoroaniline and 4-fluorobenzylidene-4 -n-alkanoyloxyaniline comprising a terminal fluorosubstituent were studied. The fluoro substituent contributes to the molecular polarizability, thus affecting intermolecular interactions and hence resulting in smectic mesomorphism. The mesomorphic properties were studied using differential scanning calorimetry and polarizing optical microscopy techniques. The mesomorphic properties of compounds studied are strongly dependent on the orientation of the imine (CH=N) linkage. The former Schiff base exhibited smectic A phase whereas the latter compound did not display any mesophase. Reversed imine linkage has caused depression of mesomorphic property in the compound studied (4-fluorobenzylidene-4 -n-alkanoyloxyaniline). The mesomorphic properties of the present compounds were compared with other structurally related series to establish the chemical structure-mesomorphic property relationship.

“…Strong demand of new liquid crystals for applications has led to the synthesis of numerous mesogens in particular, thermotropic liquid crystals [4,5]. In the previous studies, we discovered that azomethine and ester are useful connecting units for generating mesomorphism in thermotropic liquid crystals with two and three aromatic rings.…”
