Abstract:	電洞傳輸材料在鈣鈦礦太陽能電池是不可或缺的一部分，現今普及化的小分子有機電洞傳輸材料Spiro-OMeTAD其繁瑣的合成步驟及分離純化上的困難造成製程上具有較高的成本，因此許多小分子星狀電洞傳輸材料逐漸被合成出以取代Spiro-OMeTAD。而傳統合成星狀電洞傳輸材料需較多且複雜的步驟，於本文中將介紹利用鈀催化直接碳氫鍵芳香環化反應，合成各式星狀電洞傳輸材料，其利用三苯胺（Triphenylamine），3,4-乙烯二氧噻吩（3,4-Ethylenedioxythiophene）為中心和π架橋，在末端基上，我們使用具有不同烷基鏈的三苯胺（Triphenylamines），咔唑（Carbazoles），吩噻嗪（Phenothiazine），並以測量其電化學，熱性質，電洞遷移率和光伏性能。此方法可將反應步驟從先前傳統人名反應中的六個步驟減少到兩個步驟就可完成，合成出已知的星狀電洞傳輸材料[BMPA-EDOT]3-TPA及新型星狀電洞傳輸材料YC01-10並測得其光電轉換效率(PCE)達到17 %。這項研究可給予材料科學家們新的思維，可利用更加便利，並具有步驟經濟及綠色化學的方法來合成電洞傳輸材料。 ;A step-economical synthetic strategy to synthesize the star-shaped hole transporting materials which used triphenylamine (TPA) as middle core and3,4-Ethylenedioxythiophene(EDOT) as-linker. In the end group, we use some donors such as triphenylamines, carbazoles, phenothiazines with different alkyl chain to measure their electrochemical,thermal properties, hole mobility and photovoltaic performance. It is worthwhile mentioning sequential Pd-catalyzed and Sn-free direct C-H arylation reaction to synthesize the star-shape dhole-transporting material is reduced from the traditional six steps to two steps. The PCE of perovskite solar cell (PSCs) device achieves 17%. These results provide a green synthetic alternative to access the star-shaped hole-transporting materials.
