Abstract:
Novel alkanoyl ester compounds represented by general formula (I) (wherein A represents -, -O-, (II), (III), (IV) or (V), B represents (II) or (III), l and m each represents 1 or 2, provided that l and m do not represent 2 at the same time, k and n each represents an integer of 1 or more, with k > n, and R represents an alkyl group), a liquid crystal containing same, novel alkanoylphenyl compounds to be used as intermediates for preparing them, novel alkanoylbiphenyl compounds, and processes for their preparation are disclosed. The novel alkanoyl ester compounds have excellent stability to light, etc. and can take a liquid crystal form over a wide temperature range. Introduction of an optically active group into the compounds provides strongly dielectric liquid crystals showing large spontaneous polarization and rapid response. Thus, the compounds can be utilized as materials for optoelectronics-related elements.
