功能性有機小分子已被廣泛應用於半導體材料中，而傳統合成法需要較多且複雜的步驟。本研究中將利用一鍋化連續式直接碳氫鍵芳香環化反應來製備D-A-π-A形式的有機染料分子 (CYL-20及CYL-21) 與以3,4-Ethylenedioxythiophene (EDOT) 為中心結構的D-π-D-π-D形式的電洞傳輸材料 (KM01-KM07) 並分別應用於染料敏化太陽能電池與鈣鈦礦太陽能電池中，其中鈣鈦礦太陽能電池光電轉化效率可達15 %以上。本研究可給予材料科學家們新的思維，可利用更加便利，更少合成步驟的方法合成具功能性的有機小分子。;We use 3,4-ethylenedioxythiophene (EDOT), thiophene as middle core and π-linker. In the end groups, we use different donors such as triphenylamine (TPA), carbazole with different alkyl chain to measure their electrochemical, thermal properties, hole mobility and photovoltaic performance. For applications in dye-sensitized solar cells (DSSCs) and perovskite solar cells (PSCs), we demonstrate that two D-A-π-A type new organic sensitizers (CYL-20 and CYL-21) and D-π-D-π-D type hole-transporting materials (KM01-KM07) can be step-economically synthesized by one-pot reactions through sequential C-H arylations. The PCE of perovskite solar cells (PSCs) device achieves 15%. This work aims to provide facile access to high-performance organic sentizers and hole-transporting materials.
