Popis: 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 enthalpy on cooling. In contrast, (S,S)-1 did not show the unusual transition. However, a 1:1 mixture of (S,S)-1 and (R,R)-1 exhibited IsoX phase. These results suggest that the appearance of IsoX phase is attributed to a chirality-dependent molecular recognition.
