摘要

本篇論文利用Hay cross-coupling及Sonogashira coupling反應合成出具有推拉電子性質的二乙炔喹啉及苊醌系列共軛化合物，藉由螢光、UV吸收、循環伏安法及電致化學發光 ( Electrogenerated ChemiLuminescence，ECL ) 來探討這兩個系列化合物的光物理性質及電化學特性。並對其理論計算 ( Density Functional Theory；DFT-B3LYP/6-31G ) 將計算之結果與實驗結果做一比較。
在這次的研究中，我們將針對推電子取代基的強弱及乙炔基的延伸對系統在螢光、UV吸收、循環伏安法及電致化學發光性質之影響做深入的探討。

Tow series of π-conjugated bipolar compounds Butadiynyl-quinolines and Acenaphthenequinones having inherent redox centers have been synthesized and their UV-Vis absorption, fluorescence emission and electrochemical behavior are studied. Electrogenerated ChemiLuminescence of these molecule bear weak, strong is also studied. The observed electronic properties are explained by means of Density Functional Theory ( DFT-B3LYP/6-31G ) calculations. The structure-property relationships of all the molecules are discussed.
