摘要:	中文摘要 EMD 是一種多環芳香烴化合物，其優點在於化學結構相穩定不易被破壞，且是一個巨大共軛體，有助於分子內的價荷傳輸能力；另外，也具有高度的平面性，因此分子間的 π-π 堆疊能力較強，利於分子間價荷的傳輸，此優勢非常適合應用在光電領域的材料上。故本論文研究欲合成四個 EMD 系列高分子，EMDCN2TVT、EMDCN2bT、EMDF2T 以及 EMDF2bT，將受體單體 EMD 搭配不同拉電子官能基的給體單體，此外擔心其結構過於平坦而造成溶解度太差，故加入長碳鏈噻吩以增加溶解度與延長共軛長度，後續進行一系列光學性質與物性測量的探討，最後也將高分子化合物搭配不同的 n-type 與 p-type 材料混摻製成有機光伏電池元件，並測量轉換效率以及分析元件表現的結果。關鍵字: 多環芳香烴化合物、價荷傳輸能力、π-π 堆疊能力、高分子、有機光伏電池 ;Abstract EMD is a polycyclic aromatic hydrocarbon compound, which advantages is too stable to be destroyed easily. Also it is a huge conjugated monomer that helps the charge transport ability within a molecule. The ability of π-π stacking between molecules is strong because of good planarity, which benefits the intermolecular charges transfer. As mentioned above, EMD is a suitable materials for used in the field of photovoltaic. In this thesis, it intends to synthesize four polymers of EMD series, namely EMDCN2TVT, EMDCN2bT, EMDF2T and EMDF2bT, respectively. The acceptor monomer EMD is matched with different electron-withdrawing functional groups of donor monomers. In addition, to concern the structure has high planarity that causes the poor solubility, alkyl chain thiophene was added to increase the solubility and to increase the conjugation. A series of optical properties and physical property measurements were discussed subsequently. Finally, the device of photovoltaics was made of n-type or p-type polymers, and the conversion efficiency as well as the performance of the device were measured. Keywords: polycyclic aromatic hydrocarbon compounds, charge transport ability, π-π stacking, polymer, photovoltaics.
