| 제목 | Dimesogenic Compounds with a Schiff Base Mesogenic Units and a Tetramethylene Flexible Spacer |
| 초록 | A homologous series of novel liquid crystal compounds having two identical terminal Schiff base mesogenic unit and a central tetramethylene spacer were prepared. The molecular structures of the dimesogenic compounds are presented below X= -F, -Cl, -Br, -I, -CN, -CF3, -OCH3 Their thermal and liquid crystal properties of the dimesogenic compounds were studied by differential scanning calorimetry and polarizing microscopy. The final products withX= -F, -Cl, -Br, -CN and -OCH3 were enantiotropically nematic liquid crystalline. In contrast, the compounds with X= -I and -CF3 were non-liquid crystalline. The nematic forming efficiency of the groups was in the order of CN ＞ -OCH3 ＞ -Br ＞ -Cl ＞ -F. |
