| 摘要: | 合成含stilbene 官能基之條形,彎形,盤形,樹枝形,直角形分子,經由分子結構 之改變將致使分子由非液晶質變成各類型液晶質,藉以得到生成各類型液晶相 之幾何結構條件. 彎形分子之鐵電性及反鐵電性將以電場加以區分.新分子結 合液晶性質, 螢光及雙光子吸收性質, 相關的光化學及光物理之量測與探討 對發展成光學運用材料會有很大的助益. banana, disc, dendrimer, and orthoconics. Depending upon the position and the number of peripheral chains, mesophase structure changes from calamitic to columnar. This study affords the information of molecular structure-mesophase relationships. Ferroelctric and antiferroelectric proerties of the banana types will be characterized by application of electrical fields. Molecules synthesized in this study, either mesogens or nonmesogens, exhibit intense fluorescence (photo-active or electro-active) and two-photon absorption fluorescence. These materials are highly useful for optical, electro-optical, and light emitting applications. The results obtained are important for the design of these materials for applications. |
