Four azo-ester mesogens with lateral methyl were synthesized where these compounds are differed by the terminal substituents i.e. -H, -Cl, -Br and -CN. The compound with-H terminal substituent displayed nematic behavior with narrow mesophase range while electron-withdrawing groups terminated compoun...
