合成一系列含有雙苯乙炔基並有不同長度的間隔基之環氧丙烷液晶單體，並以陽離子開環聚合的方式進行聚合，得到四個含雙苯乙炔基聚環氧丙烷之側鏈液晶聚合物。所有的液晶單體及聚合物均使用核磁共振光譜儀、微差掃描卡計及偏光顯微鏡偏光測得其化學結構、熱性質及液晶相之研究。
A series of oxetane liquid crystal monomers containing tolane mesogenic groups having spacers of different lengths were synthesized and polymerized by cationic ring-opening polymerization to obtain four side-chain liquid crystals polyoxanes containing tolane mesogenic side groups. The chemical structure, thermal properties and liquid crystalline phase of the liquid crystal monomers and polymers were measured by NMR spectroscopy, differential scanning calorimeter and polarized light microscopy |
