Abstract
Novel dichiral liquid crystal compound 2-[4-((R)-2-fluorohexyloxy)phenyl]-5 -[4-((S)-2-fluoro-2-methyldecanoyloxy)phenyl]-pyrimidine ((R,S)-1) exhibits new optically isotropic phase (IsoX) with an endothermic transition enthal py on cooling. In contrast, (S,S)-1 did not show the unusual transition. Ho wever, a 1:1 mixture of (S,S)-1 and (R,R)-1 exhibited IsoX phase. These res ults suggest that the appearance of IsoX phase is attributed to a chirality -dependent molecular recognition.
