本文所合成之染料IP-101為具有高總產率之有機染料，而我們嘗試開發以其作為配位基之鈀金屬染料，其以Indole此具高莫耳消光係數之雜環作為基本架構，再引入金屬與其配位，生成4配位之錯合物染料。我們於其錯合物與原先配位基的比較上發現了明顯的紅位移現 象，而我們亦希望此現象能夠應用於染敏電池之敏化劑。 ;Since the industrial revolution, energy has dominated our lives. Among the all renewable energy resources, Dye-Sensitized Solar Cells (DSSC) have received much attention of academic and industrial due to its low-cost and simple manufacturing process. Sensitizer is one of the key components which will greatly affect the performance in DSSC; therefore, numerous researchers have developed various kinds of novel dye and achieve significant efficiency. Ruthenium-based dye was one of the best we have;however, it also led to some serious issues, such as environmental pollution and its rarity; thus, we would like to design some novel metal complex sensitizers to replace it.
The sensitizer IP-101, made up by indole derivatives possessing the advantage of high total yield, was designed and synthesized, and later play as a ligand in 4-coordinated palladium complex. Compared with the original ligand, the UV-Vis spectrum of palladium complex shows obviously red-shift in absorption band which could be beneficial to sensitizers of dye-sensitized solar cells.
