Substituent effects of the benzoyl group were investigated on the mesogenic properties of 2-aminobenzoyl-5-alkoxytropones. The X-ray crystallographic struetural analysis of 5-butoxy-2-(4-methoxybenzoyloxy)aminotropone revealed a CH-π interaction between the benzoyl π-system and the β-hydrogen of the butoxy group on the tropone ring of a neighboring molecule and a π-π interaction between two tropone rings. When four fluorine atoms were introduced on the benzoyl group, the mesogenic properties were reduced. The X-ray diffraction study of 5-butoxy-2-(4-methoxyperfluorobenzoyl)aminotropone indicated that the angle between the perfluorobenzene ring and the amidocarbonyl group was about 45°.
