| Summary: | 碩士 === 國立交通大學 === 應用化學研究所 === 98 === This thesis, divided in two parts, presents synthetic work of novel electron accepting materials based on fullerenes that contain chalcogenophenes for organic solar cells and designs a new type of ruthenium complex and then synthesis.
For the synthesis of novel electron accepting materials, we use several ways to make novel electron accepting materials. First, we alkynes to react with phosphines and afford [60]fullerene derivatives. Second, we synthesized open-cage fullerences by organic reactions, so-called “molecular surgery” methods. Third, we made of cyclopropanated fullerenes through Bamford-Stevens reaction, as that of preparing PCBM. Fourth, we prepared compounds with electron-rich and electron-withdrawing groups. Fortunately, we modified the phenyl group of PCBM with furyl moiety and found that its power conversion efficiency can be as high as 3.11 % while fabricated with polymer P3HT.
For dye-sensitized solar cell materials, designed and synthesized of a new type of ruthenium complexs with pyridine-pyrrole-pyridine ancillary ligands.
