  This invention provides a novel alkanoyl ester compound represented by general formula (I): ##STR1## (wherein A is of --, --O--, ##STR2## B is ##STR3## l and m are 1 or 2 provided that both are not simultaneously 2, k and n are an integer of 1 or more, respectively, provided that k>n, and R is an alkyl group), a liquid crystal composition containing this compound, a novel alkanoylphenyl compound or a novel alkanoylbiphenyl compound as an intermediate for the production of the above compound, and a method of producing the same. These novel alkanoyl ester compounds are excellent in the stability against light and the like and can take a liquid crystal state at a wide temperature range. Particularly, these compounds form liquid crystals of ferroelectricity having a large spontaneous polarization and a fast response rate by introducing an optically active group into the compound, so that they develop a very excellent effect as a starting material for optoelectronics and its related elements.

  这项发明提供了一种新型的烷酰酯化合物，其通式表示为（I）：##STR1##（其中A为--，--O--，##STR2## B为##STR3##，l和m为1或2，但不能同时为2，k和n分别为1或更多的整数，且k>n，R为烷基），含有该化合物的液晶组合物，作为上述化合物生产的中间体的新型烷酰苯化合物或新型烷酰联苯化合物，以及生产该化合物的方法。这些新型烷酰酯化合物在光稳定性等方面表现出色，并且可以在广泛的温度范围内呈液晶状态。特别是，通过在化合物中引入光学活性基团，这些化合物形成具有大自发极化和快速响应速率的铁电液晶，因此它们作为光电子学和相关元件的起始材料具有非常出色的效果。
