Abstract: | 本篇論文合成了以吡咯並[3,2-b]吡咯為中心的一系列化合物,在其二、五號位上分別接上三苯胺、咔唑及噻吩等基團,探討其電化學、光物理與光化學性質。其中化合物4具有電聚的潛力,已初步探討了其電聚合與電致變色的行為。而化合物1在具有鹵化物的環境下有光化學反應變色的情形,以UV-Vis-NIR光譜追蹤分析推測出其可能的反應機制,並進一步用作鹵化物偵測,以肉眼辨識變色水中的三氯甲烷濃度最低可達8 ppm。此外,此一系列化合物皆有很強的螢光強度,在光電材料的應用上是具有潛力的新型染料。 A series of compounds with pyrrolo [3,2-b] pyrrole-centered have been synthesized, containing triphenylamine, carbazole, and thiophene group at the 2, 5-position. The electrochemical, photophysics and photochemistry properties were investigated. Compound 4 have show potential for electrochemical polymerization, and its electrochromic mechanism has been studied. Compound 1 in the environment with halides proceeds a photochemical reaction and is observed change color. The possible reaction mechanism have been studied by UV-Vis-NIR spectrum analysis, and further used to detect halide, which can visually identify chloroform in water to lowest concentration of 8 ppm. Additionally, this series of compounds have strong fluorescence intensity, having potential to be novel dyes in the application of photovoltaic materials. |
