含羧酸基團之不對稱苝環小分子合成、性質探討及其在染料敏化太陽能電池上的應用

Synthesis and Characterization of 1-aryl-7-(4-carboxyl-phenyl)-substituted Perylene Bisdiimide and the Applications on Dye-Sensitized Solar Cells

指導教授 : 梁 文 傑

摘要


本論文主要是探討具有羧酸基團不對稱苝環小分子之光電行為。建構以苝環為主體的小分子,在苝環7號位置引入苯甲酸基團,1號位置引入電子豐盈之芳香族取代基,以增加苝環中心電子密度,提高電子轉移至二氧化鈦導帶的機率,並觀察取代基效應對該分子之光物理特性以及電化學行為的影響。 由於該系列化合物具有可見光良好吸收的特性,可以作為染料敏化太陽能電池(DSSC)元件中的染料。此外,羧酸基團的修飾可增強與二氧化鈦之間的作用力,期能有助於提升太陽能電池元件的效率。

In this thesis, a series of unsymmetrical small molecules containing perylene bisdiimide (PDIs) with carboxylic acid functional group was synthesized. Benzoic acid was connected to perylene bisdiimide at 7 position to form the binding with TiO2 and electron-rich aromatic function group was connected to perylene bisdiimide at 1 position to increase electron density of perylene core. The substituent effects on the photophysical and electrochemical properties of these unsymmetrical aryl-substituted perylene diimides have been carefully studied. Because of the properities of broadening visible absorption spectrum of these molecules, we use these molecules as the dye of Dye-Sensitized Solar Cell (DSSC).
