In the present paper, we describe the synthesis and characterization of six new bent -shaped molecules carrying
the 2-methoxy-3-cyanopyridine as a core possessing an outer phenylene unit at the lengthening arm with different alkoxy
chain lengths (C-10 and C-12). Mesomorphic behaviors of the new compounds were investigated using optical
polarizing microscope and DSC studies. Also, the effect of structural variables on mesogenic properties was studied.
All the new cyanopyridine derivatives showed good liquid crystalline properties and exhibit smectic phase.
