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.
