| dc.description.abstract | 近年來，聯合國大力提倡永續經營的理念，各界人士亦紛紛投入心力於再生能源的發展，其中，因鈣鈦礦太陽能電池(perovskite solar cells, PSCs)展現出高效的光電轉換的性質，並具有原料容易取得、合成方法簡易，且價格低廉等優勢，脫穎而出，出現在大眾的眼中，成為各研究團隊熱門的研究主題。
其中，富含電子予體的S,X-駢芳香雜環(S,X-heteroacene)擁有高度平面性、高導電性，以及熱穩定性等特點，並且在其他光電材料中的領域也取得不錯的成績。然而，在翻閱文獻的過程，發現較少提及此化合物於鈣鈦礦太陽能電池中的應用，因此，本研究將著重於此化合物與不同雜原子結合作為橋梁製成的核心，連接末端基並設計出D-π-D的架構，同時，改良多步驟的傳統合成方法，過往多以人名反應合成，但此方法步驟冗長且需要使用會對環境造成影響的試劑，故本研究將以省步驟的合成途徑作為研究主軸，製備出電洞傳輸材料(hole transporting materials, HTMs)，並應用於反式的鈣鈦礦太陽能電池之中探討其對光電轉換的效率。
本篇將直接活化3-溴噻吩上二號位上的碳氫鍵，並與1,4-二溴-2,5-二碘苯進行碳氫鍵碳碘鍵耦合反應得到關鍵building block，再與不同之雜原子進行合環反應，由此製備出S,X-駢芳香雜環之核心，最後連接特定的末端基後，得到了四種新型的對稱結構之有機小分子，並作為電洞傳輸材料，應用於反式的鈣鈦礦太陽能電池元件上。 | zh_TW |
| dc.description.abstract | In recent years, the United Nations has been vigorously advocating the concept of sustainable development, prompting people from various fields to devote their efforts to the development of renewable energy. Among these efforts, perovskite solar cells (PSCs) have stood out and captured public attention due to their high power conversion efficiency, ease of obtaining raw materials, simple synthesis methods, and low cost. As a result, PSCs have become a popular research topic for many research teams.
S,X-Heteroacene, which is electron-rich, possess characteristics such as high planarity, high conductivity, and thermal stability. It has also achieved remarkable results in other optoelectronic material fields. However, there is limited literature on the application of these molecules in PSCs. Therefore, this study will focus on the core of this molecule combined with different heteroatoms, designing a D-π-D structure by connecting terminal groups and improving the traditional multi-step synthesis methods. Previous methods mainly relied on named reactions, which are lengthy and require reagents that can impact the environment. This research will focus on a streamlined synthetic route to prepare hole-transporting materials (HTMs) and apply them to PSCs to explore their effect on photoelectric conversion efficiency.
In this study, we directly activated the C-H bond at the 2-position of 3-bromothiophene and perform a C-H/C-I coupling reaction with 1,4-dibromo-2,5-diiodobenzene to obtain a key building block. This molecule will then undergo a cyclization reaction with different heteroatoms to prepare the core of the S,X-heteroacene. Finally, by connecting specific terminal groups, five new symmetric organic small molecules were obtained. These molecules were used as HTMs and applied to inverted PSCs. | en_US |
