During our investigations of the synthesis of ferroelectric liquid crystal compounds containing 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 is the first report concerning a liquid crystalline compound with this type linkage.The thermal stability of the mesophase is reduced upon changing from the -C(O)-O-linkage to the -C(O)-S-O-linkage.The synthesis and properties of this compound are discussed in detail.
