本論文利用鈴木耦合聚合反應合成一系列具D-A結構之共軛高分子，其中以萘二醯亞胺作為受體，3,6及2,7位置取代之咔唑作為施體，並分別以四苯乙烯、氟化四苯乙烯及長碳鏈取代咔唑單體之9號位置。透過紫外–可見光吸收光譜和循環伏安法測量高分子之光學及電化學性質，藉由高分子之最大吸收波長可觀察到由於分子內電荷轉移作用導致3,6位置之咔唑較2,7位置紅移，氟化四苯乙烯取代之咔唑因為分子內立體阻礙造成最大吸收波長藍移，而D-A結構產生較強的分子內電荷轉移作用，因此高分子之能隙皆低於2.0 eV。利用熱重分析儀和示差掃描熱量儀測量高分子之熱穩定性及結晶性質，因為其多芳香環結構而使高分子均具有良好的熱穩定性。另外，將高分子製作成元件並分析其電學性質，可得其遷移率並推測為p型有機半導體材料。

A series of new D-A alternating copolymers containing naphthalene bisimides as donor and triphenylvinylphenyl, fluorinated triphenylvinylphenyl or alkyl chain substituted 3,6- or 2,7-carbazoles as acceptor were synthesized by Suzuki-Miyaura polymerization. The optical and electrochemical properties were investigated by UV-Vis absorption spectroscopy and cyclic voltammetry. The 3,6-carbazole-based polymers exhibited red-shifted compared to 2,7-carbazole-based polymers due to ICT interaction, and the fluorinated tetraphenylethene substituted carbazole-base-polymer shows a little blue-shifted absorption wavelength because of the steric hindrance. The band gap of the copolymers is less than 2.0 eV possibly owing to the strong intramolecular charge transfer between carbazoles and naphthalene bisimides. The thermal properties were examined by thermogravimetric analysis and differential scanning calorimeter. The polymers revealed high thermal stability as the structure of the polymer backbone containing large amounts of the fused aromatic rings. In addition, the polymer was made into device and determined the electrical property to obtain the mobility, and inferred to p-type organic semiconductor material.
