of ferroelectric liquid crystal compoundscontaining a fluorenone nucleus, the formation of a novel compound having a –C(O)–S-O– linkage was discovered as a by-product when a derivative of fluorenone carboxylic acid was treated with thionyl chloride and a phenol. This compound also exhibited ferroelectric liquid crystal properties. Compounds with a –C(O)–S–O– linkage have been little reported; this
