摘要

本次研究為合成塞吩之衍生物，並分為以下2個主軸，（1） 藉由改變賽吩3號位置之烷基鏈，合成出聚3己基塞吩(P3HT), 聚3辛基塞吩(P3OT), 聚3癸基塞吩(P3DT), 聚3丑基塞吩(P3DDT)；（2） 利用Donor-Acceptor 之觀念，以塞吩為Donor，苯歐唑之衍生物為Acceptor，聚合出窄能係共聚物，並探討高分子之紫外光-可見光吸收光譜，光致發光螢光光譜，利用循環伏安計計算出最高填滿及最低未填滿能階，並將高分子製作成太陽能電池元件，利用原子力顯微鏡觀察薄膜表面，及量測其電流-電壓曲線計算出元件之效率。

The research project of this thesis is mainly the synthesis of poly thiophene and its application on polymer solar cells. In the synthesis section, we divided into two topics to discuss. For the first topic, we changed the alkyl group of thiophene 3 position to synthetize 4 different poly(3-alkylthiophene)(P3AT) with poly(3-hexyl thiophene) (P3HT), poly(3-octyl thiophene) (P3OT), poly(3-decanal thiophene) (P3DT),and Poly (3- dodecylthiophene-2,5-diyl) (P3DDT). For the second topic, we used the donor-acceptor concept with thiophene as the donor and benzo[c][1,2,5]thiadiazole, 2-phenylbenzo[d]thiazole, 2-(benzo[d]thiazol-2-yl)phenol as the acceptor to synthetize the low band gap polymer. Finally discussed the UV-vis spectrum, photoluminescence, calculated the HOMO, LUMO by cyclic voltammetry, and fabricated the photovoltaic devices to discuss the I-V curve.
