摘要：
Hexenediynes, suitable for use in liquid crystal systems, have the formula:
wherein R¹ and R² are the same or are different and each is an alkyl or alkoxy group; ring A and ring B are the same or are different and each is a 1,4-cyclohexylene or 1,4-phenylene group; and X is a hydrogen or fluorine atom.
wherein R¹ and R² are the same or are different and each is an alkyl or alkoxy group; ring A and ring B are the same or are different and each is a 1,4-cyclohexylene or 1,4-phenylene group; and X is a hydrogen or fluorine atom.
