本研究之目標是合成以 Triphenylamine 及 Thiophene 衍生物為建構單元之全有機小分子光敏化染料，因為有機小分子與被廣泛使用之釕金屬錯合物，兩者相較之下，有機小分子染料有著較高吸收係數及無須使用貴重金屬元素的好處。我們運用了兩種有機合成法，先以 Vilsmeier-Haack reaction 將 Triphenylamine (TPA)、N,N′-Bis(3-methylphenyl)-N,N′-diphenylbenzidine (TPD)、2,2′-Bithiophene (BT) 及 3,4-ethylenedioxythiophene (EDOT)接上所需的醛基數目，再利用 Knoevenagel condensation reaction，是以 TPA、TPD、EDOT 及 BT 所接上的醛基與
Rhodanine-3-acetic acid 上的亞甲基進行親核性加成反應隨後再進行脫水反應，即
可得我們所需的全有機小分子光敏化染料，隨後再以 Rhodanine-3-acetic acid 上的
羧酸和二氧化鈦奈米粒子進行自組裝作用。此外我們也將此光敏染料運用於電致
色變元件上。分別探討接上不同數目的 Rhodanine-3-acetic acid 之染料組成染料敏
化太陽能電池與電致色變元件的效能差異。

Triphenylamine (TPA,TPD)- and ethylene dioxyl thiophene (EDOT,BT)-based metal-free organic dyes were synthesized and employed to the dye-sensitized solar cells (DSSCs) in this study. Metal-free organic dye, compared to the ruthenium-based photo-sensitizer in the dye-sensitized solar cells, has the advantages of high absorbance coefficient and without using expensive metal. We employed two kinds of organic synthetic methods. Different number of aldehyde groups were first linked on the molecules of TPA,EDOT,EDOT and BT by using the Vilsmeier-Haack reaction. Then, the metal-free organic dyes were obtained through the nucleophilic addition and dehydration between the aldehyde groups on TPA,EDOT,EDOT and BT and the methylene of rhodanine-3-acetic acid by using the Knoevenagel condensation reaction. The two dyes were anchored on the surface of titanium dioxide nanoparticles using the carboxylic acid of dyes by means of the self-assembly method. Furthermore, these dyes were also used to assemble the electrochromic device. A vertical integration of dye-sensitized solar cells and electrochromic devices was fabricated and subjected to measure the performance of the integrated devices.
