Paper Abstract

The basic structure of 4-[(4'-decyloxybiphenyl-4-yl)-oxycarbonyl]-phthalimide acetic acid methyl ester forming the modulated smectic C phase was modified by introducing changes into the biphenyl group or the substituent attached to the nitrogen atom. The decyloxy chain has been also changed to the carbonyldecyloxy chain. The liquid crystalline phase behaviour of the new ester imide derivatives was examined by DSC, polarized optical nilcoscopy and X-ray diffraction methods. It was found, that addition of a polar group suppressed the smectogemc properties. The compounds having —COO- or —CHN- group inserted between the phenyl rings, formed the nematic phase only.
