Description

<p>We synthesized and evaluated liquid crystalline (LC) phases of novel benzoic acids with different alkylthio groups at each para-position. Their LC phases were characterized with polarizing optical microscopy (POM), differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD). The present molecules solely form a nematic (N) regime, owing to spontaneous carboxylic dimerization. It was found that the number of carbons in the alkylthio groups strongly correlated with transition temperatures as well as nematogenic stability; odd-even effects. Based-on WAXD measurements with aligned specimens, an alkylthio analogue exhibited the enhanced cybotactic clusters compared to an alkoxy analogue.</p>
