利用 Suzuki 耦合反應於以三苯胺為主體之多孔性共軛高分子之合成、性質探討及其在電致變色上的應用

Abstract

在本論文中我們利用 Suzuki 耦合反應合成了一系列以三苯胺為主體帶有磺酸根的有機鹽類分子。由於目標分子帶有磺酸根，所以我們藉由加入界面活性劑使其形成一微胞(micelle)結構，並用電聚合方式誘導分子發生聚合反應，形成一具有奈米尺寸的多孔性共軛高分子薄膜。由於其所形成的高分子薄膜在氧化還原過程中具有電致變色的特性，於是我們將其應用在黑色電致變色上。

In my study, we use Suzuki coupling reaction to forming a series of triphenylamine-based monomers that have sulfonate segment in the side chain. Due to the sulfonate segment inside, we can add surfactant in solution to let molecules become nanomicelles. The other is triphenylamine group can be polymerized by electropolymerization and so we use this method to obtain conducting microporous polymer films with nano-sized. Because the films have electrochromic properties, we use it to black electrochromic device, which is rarely reported so far.
