Abstract

The synthesis and characterizations of four symmetric and unsymmetric achiral banana-shaped esters possessing the terminal trimethylsilyl group are described. The chemical structures are confirmed by IR, NMR techniques and further compounds have been examined for liquid crystal properties by polarized light optical microscopy (POM) and differential scanning calorimetry (DSC). In unsymmetric molecule B1 mesophase has been observed. The remaining compounds are hard to exhibit liquid crystalline property.
