摘要

本篇論文之主體大環乃針對本實驗室在2017年發表於J. Phys. Chem. C 中代號的 LS-11染料進行結構上修飾，特別是對推電子基基團加以改性，成功合成出LS-22及LS-23兩支染料，推電子基基團乃是參考本實驗室在2020年Energy Environ. Sci.中代號的LS-45染料，皆為diarylamino group，不同的是，LS-22連接於anthracene；LS-23則連接於naphthalene，拉電子基部分皆以benzoic acid作為錨定基團。
LS-22及LS-23兩支染料皆已通過核磁共振光譜儀1H-NMR及13C-NMR、MALDI TOF 質譜儀及元素分析的鑑定，確認了這兩支染料的結構及純度。
藉由 DFT 理論計算、電化學性質、紫外光-可見光譜儀的協助，我們觀察到 LS-22 及 LS-23 染料具有成為染料敏化太陽能電池中敏化劑的優勢。

In this work, two bacteriochlorin dyes (denoted as LS-22 and LS-23) were successfully synthesized, characterized, and studied.
The structures of the LS-22 and LS-23 dyes are based on the LS-11 dye (J. Phys. Chem. C, 2017) with structural modification. The electron-donating groups of the new dyes are the diarylamino group, whereas the electron-withdrawing anchors are a benzoic acid.
Both the LS-22 and LS-23 dyes have been characterized by 1H and 13C-NMR, MALDI TOF mass spectrometry and elemental analysis.
Through DFT calculations, electrochemical measurements, UV-visible absorptions and fluorescent emissions, the experimental data show that the LS-22 and LS-23 dyes are adequate dyes for dye-sensitized solar cells.
