摘要

本篇論文分為兩部分：第一部分是有關於有機發光材料。該部分先透過計算化學確認主體結構後，再利用官能基團的變動來達到修正最大發光波長的目的。這一部分之有機發光材料是以Buchwald–Hartwig偶合反應來連接供體以及受體，並在中間以苯環隔開。藉由引入不同之官能基團，合成一系列以咪唑[1,2-a]嘧啶結構為主體之螢光材料。該系列螢光材料分別溶於乙酸乙酯所測得之最大吸收波長範圍為330~370 nm；最大螢光放射波長為415~511 nm。
第二部分是有關於偶氮染料，該部分是想設計一系列的偶氮染料，該系列的特點是只需要一次重氮化反應就可得到含括三種顏色（橘色、紅色以及藍色）的染料。最終，再分別從三種顏色之染料中，挑選穿透度差值（ΔT）表現最佳的三個偶氮染料，依照不同比例混合成黑色染料並確認其ΔT。

This thesis consist of two parts. One is related to organic light-emitting materials; by computational study, the structure of target molecule was chosen first, and then its functional group was modified to achieve the maximum emission wavelength. The organic light-emitting materials were prepared by the Buchwald–Hartwig coupling reaction between donor and acceptor; two corresponding moieties were linked by a benzene ring. Using different functional groups, we thus prepared a series of fluorescent materials with imidazole [1,2-a] pyrimidine unit as the main body; the maximum absorption wavelength range of this series of fluorescent materials dissolved in ethyl acetate is 330 ~ 370 nm; the maximum fluorescence emission wavelength is 415 ~ 511 nm.
The second part is realted to azo dyes, which promote us to design a series of azo dyes with orange, red and blue colors and can be prepared by only one diazotization reaction. Among them, we select three azo dyes that contain best transmission variation (ΔT), mix them in different ratio to give black dyes and study their ΔT.
