"1,4氫吡咯並[3,2-b]吡咯之二號位及五號位雙取代基系列化合物其合成及光電性質之探討"

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.
