Abstract
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.
