摘要

本論文探討兩個系列的菌綠素染料之電化學性質，首先是可用於光療法之菌綠素染料(LS-01、LS-01’及LS-01’’)，此系列染料的差別為羧酸根的多寡，可用來探討羧酸根對於菌綠素大環之影響。另一系列則是可應用於染料敏化太陽能電池之菌綠素染料，可分為三個方向探討，第一方向探討菌綠素苯環於para-位置修飾t-butyl基團之菌綠素染料(LS-21)；第二方向是以LS-11為基準，改變其錨定基團(isophthalic acid, LS-16)或者推電子基(fluorene group, LS-17)。第三方向是三種蒽取代基之菌綠素染料(LS-43、LS-44及LS-45)，另外再修飾苯並噻二唑(BTD)基團延伸共軛系統 (LS-12、LS-40、LS-41及LS-42)。
在元件方面，含有苯BTD之菌綠素染料LS-12(3.78%)、LS-40(3.08%)、LS-41(0.67%)及LS-42(0.77%)之光伏性質並沒有比預期來的好，均低於未修飾BTD基團的染料LS-11(5.35%)、LS-43(4.62%)、LS-44(4.39%)及LS-45(6.03%)，意味著BTD基團可能並不適用於現在的大環主體LS-00，懷疑是因為BTD基團加劇了染料分子的堆疊現象，進而影響太陽能電池之效能。

In this work, we study the electrochemistry of two series of bacteriochlorins s by CV and DPV. For the first series, it is for phototherapy. We examine the electrochemical behaviors of bacteriochlorins with increased carboxylic acid groups (LS-01、LS-01’ and LS01’’). For this series is the second series is for dye-sensitized solar cell. This part of study can be devided into three directions. The first direction focuses on bacteriochlorins with t-butly group at para- positions of phenyl group(LS-21). the second direction focuses on two novel bacteriochlorins substituted with isophthalic acid (LS-16) or fluorene group (LS-17) based on LS-11. The third direction focuses on three novel free bacteriochlorins substituted with anthracene (LS-43、LS-44 and LS-45),or changing the substituents near the anchoring group with benzothiadiazole (BTD) group (LS-12、LS-40、LS-41 and LS-42).
Photovoltaic performance of bacteriochlorins bearing a BTD group(LS-12、LS-40、LS-41 and LS-42). This implies that are lower than those of the bacteriochlorins without the BTD group. This implies that BTD group may not be applicable to bacteriochlorins at the moment. It may be attributed to the planar BTD unit increasing dye-aggregation, causing the drop of the efficiencies of solar cells.
