摘要

在本論文中，我們以二苯胺為主體合成出一系列胺類衍生物的染料，並且利用 D-π-A的概念，以二苯胺、噻吩，做為推電子基，苯環和共軛雙鍵作為電子傳遞的π架橋，而氰基羧酸為拉電子基。另外，在二苯胺的修飾基團上，我們加入降莰烷(Norbornane)、環己烷等疏水類烷基類基團，合成一系列新型有機染料。本篇論文主要探討不同的修飾基團對於應用在染料敏化太陽能電池上的光電轉換效率之影響。
物理性質部份，我們測試每個有機染料的個別吸收光譜、螢光激發光譜以及電化學，同時也將其應用於染料敏化太陽能電池元件，利用太陽光模擬系統來進行光電轉換效率的測試。

In this thesis, we have synthesized a serious of novel organic dyes base on diphenylamine. The main strategy is D-π-A structure, the diphenylamine for electron donor, phenyl and conjugated moiety for electron bridge, with cyanoacetic acid for acceptor. Besides, to confirm the retarding of charge combination from electrolyte, the alkyl-functionalized groups were joined like norbornane、cyclohexane in modified group for the function of steric hindrance.
All of these compounds were characterized by UV/VIS spectrophotometer, fluorescence spectrophotometer and cyclic voltammetry. Also be applied in dye-sensitized solar cell components, and the power-conversion efficiency was measured by the AM1.5 simulated solar light system.
