碳簇與釕金屬化合物之反應與性質探討

Abstract

本論文針對有機太陽能電池的兩大領域中的材料進行合成與探討，在有機光伏電池方面做電子受體材料的合成及光電性質的研究，在染料敏化太陽能電池方面做釕金屬錯合物的設計與合成。 電子受體的改質使用了幾種類型的反應機制，第一種以甲酯基旁含有炔的化合物與三級膦和碳六十反應改質為三環或五環的結構、第二種以狄耳士－阿德爾、逆回[2+2+2]、照光氧化開環及亞胺化反應來破壞碳六十或碳七十結構、第三種以腙化物與碳簇進行Bamford-Stevens 反應得到改質PCBM為含有呋喃的三環產物、第四種為將不同芳香族的甲酯化四碳鏈碳六十衍伸物進行狄耳士－阿德爾和逆回[2+2+2]反應改質為同時具有推拉兩種官能基團的碳六十衍伸物。將上述不同的產物送測元件效率，目前以化合物33和P3HT 掺混後能量轉換效率可以達到3.11 %，具有不錯的效率。 另外設計出中間為吡咯(pyrrole)的三牙配位基期待與dcbpy (4,4’-dicarboxy- 2,2’-bipyridine) 和 NCS形成新型的釕金屬錯合物。

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.
