Abstract Two new types of liquid crystals, 5-(4-alkanoylaminophenyl)-2-alkanoylaminotropones and 5-(4-alkanoylaminophenyl)-2-alkanoyloxytropones, were prepared. The former showed the smectic A phase and the latter did the smectic A and C phases. The 1H NMR spectra indicated the former to be in intramolecularly hydrogen-bonded L-shaped alignment.
