Abstract

在本論文中,我們合成了一系列含有苯胺的苝分子衍生物,分別為 Di(2An)PDI、Di(3An)PDI、Di(4An)PDI 三種苝分子衍生物。在研究室先前的研究中指出,苯胺取代基可進行電聚合反應,因此我們以電化學的方法對苝分子衍生物進行電聚合反應。電化學與紫外光-可見光光譜的實驗結果顯示, Di(2An)PDI、Di(3An)PDI、Di(4an)PDI 溶於 CH2Cl2 均可以在 Pt、GCE、ITO 及 Au 電極表面進行電聚合反應。而電聚合的電位範圍及圈數,均會影響到薄膜的電化學訊號,為此藉由實驗找出這三種苝分子衍生物的最佳電聚合的電位範圍與圈數。各個電聚合而成的薄膜,我們利用依序改變掃描速率的方式,對薄膜進行穩定性的測量。這些苝分子衍生物在 ITO 表面所形成的電聚合薄膜,其吸收光譜性質與溶於溶液中的苝分子衍生物的吸光性質有相似性,表示電聚合反應不會改變這些苝分子衍生物的 π 共軛系統。此外,還利用 SEM / EDS 觀察聚合在電極表面上的薄膜的表面形態與組成。 ; In this thesis, we studied a series of perylene diimides bearing an aniline substituent, namely Di(2An)PDI, Di(3An)PDI and Di(4An)PDI. Previous studies showed that the aniline substituent could undergo electro-polymerization reaction. Electrochemical and UV-Visible experiments show that Di(2An)PDI, Di(3An)PDI and Di(4An)PDI can be successfully electro-polymerized onto Pt, GCE, ITO and Au electrode in CH2Cl2 solution. The optimal conditions of electro-polymerization for each compound are investigated. ; 碩士
