Abstract
A benzoic acid derivative having a long flexible fluorinated chain is synth esized. The material dimerizing through hydrogen bonding shows a smectic C phase at room temperature. The acid/base complex with 4,4'-dipyridyl exhibi ts a thermotropic liquid crystalline cubic phase. Flexibility of the fluori nated substituent and incompatibility with the hard aromatic cores are cruc ial factors to form a cubic phase.
