陰離子效應對三芳香胺之吡啶鎓鹽及其衍生物聚合物光電行為之探討

Abstract

本論文分成四個章節，第一章為總體序論。 第二章探討了不同尺寸陰離子的置換對發光強度及發光特性的影響。選擇發光強度最強的材料來製作電致螢光變色元件，成功製備出橘黃色發光材料的電致螢光變色元件。這些元件以小分子型的TPA-CN-BF4為材料，利用其聚集誘導放光的性質，將元件製成交聯型膠狀結構，從而增強材料的發光強度。在元件開關時，實現了高達145倍的發光對比度。 第三章是由第二章的單體所衍生出的聚吡啶鎓鹽及其發光性質和電致變色性質之探討。 第四章為總結論。本論文探討透過置換不同陰離子，其材料發光效率、發光性質和電致變色與螢光變色之性質。

There are four chapters in this thesis. An overview is given in Chapter 1. Chapter 2 examines the effects of anion sizes on the characteristics and intensity of photoluminescence. The material demonstrated an orange-yellow emission, which was successfully created by selecting the structure with the highest quantum efficiency (ФPL) to fabricate electrofluorochromic devices. Utilizing the aggregation-induced emission (AIE) characteristics of the small molecule TPA-CN-BF4, these devices create a crosslink gel type that increases photoluminescence intensity. During switching, the gadget reached a photoluminescence contrast ratio (Ioff/Ion) of 145. Chapter 3 explores the photoluminescent and electrochromic properties of poly(pyridinium salt) derivatives synthesized from the monomer in Chapter 2. Chapter 4 is the general conclusion. This thesis investigates the effects of anion on the quantum efficiency, electrochromic and electrofluorochromic properties of materials, and luminescence efficiency.
