摘要: | 本篇論文以噁唑為主體,建構出兩個系統。第一個系統建構出噁唑小分子與側鏈噁唑高分子。第二個系統建構出噁唑與茀的共聚高分子。並藉由分子螢光與循環伏安法來瞭解分子間的特殊構型及其物理性質。
另外合成出分別具有噁唑基團的小分子和以三苯胺基團與茀的共聚高分子,發現此組合在固相下之激發錯體現象。我們發現在室溫下此組合與高分子基質相分離時不會形成激發錯體,經由控制溫度能觀察到激發錯體生成的現象,並以分子螢光與表面分析的方法瞭解激發錯體之形成機制。 We use oxadiazole as the main core to construct two systems in this thesis. The first system to construct oxadiazole small molecules and polymer with side chains of oxadiazole. The second system to construct of oxadiazole with fluorene copolymer. These molecules are identified by fluorescence and cyclic voltammetry to understand the molecular conformation and its special physical properties. In additon, we synthesized two compounds. One contains oxadiazole groups, the other includes triphenylamine and fluorene. We found exciplex in two compound combination in solid phase. It does not form exciplex when phase separation in this combination and polymer matrix at room temperature. By controlling the temperature can be observed exciplex phenomena. By using fluorescence and surface analysis methods to understand the formation mechanism of exciplex. |
