摘要：
A benzoic acid derivative having a long flexible fluorinated chain is synthesized. The material dimerizing through hydrogen bonding shows a smectic C phase at room temperature. The acid/base complex with 4,4'-dipyridyl exhibits a thermotropic liquid crystalline cubic phase. Flexibility of the fluorinated substituent and incompatibility with the hard aromatic cores are crucial factors to form a cubic phase.
