説明

Structural analyses are indispensable for elucidating liquid crystal phases; however, standard techniques, such as X-ray analysis, Raman, IR, and NMR, have some limitation due to its fluidity. It also requires accurate temperature control since a liquid crystal phase transition only occurs at a specific temperature. In this study, simultaneous differential scanning calorimetry (DSC)-Raman measurements were performed on N-(4-methoxybenzylidene)-4-butylaniline (MBBA), which is known to be a thermotropic liquid crystal. We showed, together with macroscopic information from DSC and microscopic information on the molecular vibration from Raman spectrum analysis can be obtained. From a detailed analysis (from careful examinations), the results suggested that in the process of phase transitions, intermolecular and intramolecular interactions are not transforming uniformly, but different processes for each fragment in the molecule are occurring.
