Abstract
The novel banana-shaped liquid crystal materials namely 4-methyl-1,3-benzenedicarbonic acid esters have been synthesized and their mesomorphic properties have been studied. The differential scanning calorimeter investigation showed that these compounds decomposed at temperature above 200°C, so the thermograph measurements in regime of cooling from isotropic liquid have not made. Data of polarizing microscopy show that all prepared compounds are mesomorphic and form mesophase in narrow temperature interval, which have not identified.
