Abstract:	有機光伏打電池具有製作成本低廉、元件製作簡單及可撓曲等特點，但過去數十年來相關的發展卻始終受限於轉換效率過低的問題，因此為了能夠更進一步的了解高效率光伏打電池材料的特性，我設計了一系列偶極性的indenoindene衍生物，這些分子的結構非常特殊，分別將不同的多電子與缺電子片段同時整合在indenoindene的兩側，也因此，我預期它們應該會具有很不錯的電洞傳遞效率、電荷分離能力與高消光係數，這些都是作為高效能的p型有機光伏打電池材料所必備的條件；雖然如此，它們的合成卻相當簡單，只要透過4至5個步驟的反應，就可以將買來的材料轉換成目標產物。由於至今仍尚未有人徹底地研究過上述這些分子的光物理、電化學與熱穩定性等行為，所以我也將在結束合成工作之後逐步地進行相關的探討，並測試它們在未來作為新穎有機光伏打電池材料使用的可行性。 Organic photovoltaics (OPV) have the merits of low-cost, flexible, and simple fabrication. However, their developments, especially for small molecule OPV, were inhibited by the low conversion efficiencies in the past few decades. In order to have an overview of the demands for appropriate OPV materials, I designed several types of dipolar materials based on indeno[2,1,a]indene template (Figure 1). The proposed syntheses are promising and can be easily derived from commercial chemicals in 4-5 steps. According to the unique geometry of dipolar indenoindenes incorporating efficient electron donating and accepting groups at the opposite sides of central segment, they will have good to excellent hole mobilities, the ease of charge separation, and high extinction coefficients, by which all the essential requirements for p-type materials can be satisfied. A systematic research progress has been set up for the detailed study of their photophysical, electrochemical, and morphological behaviors which no one ever understood clearly. Furthermore, the original aspiration of the potential OPV application will be carefully examined.
