| Summary: | 碩士 === 國立暨南國際大學 === 應用化學系 === 106 === In this work, LS-44, LS-45, LS-01' and LS-01'' were successfully synthesized, characterized, and studied.
The macrocycles of this thesis are chromophores with structurally modified structures of the LS-11 dye (J. Phys. Chem. C, 2017). The electron-donating groups of the new dyes are based on those of our 2016 Energy Environ. Sci. paper, namely the LWP13 and LWP14 dyes. LS-11, LS-44 and LS-45 all use a benzoic acid as the anchor group. The electron-donating group of LS-11 is 4-ethynyl-N,N-dioctylaniline; LS-44 uses a dioctylamino group; and LS-45 uses a diarylamino group.
Both LS-44 and LS-45 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-44 and LS-45 dyes are adeguate dyes for dye-sensitized solar cells.
