Abstract:	本文第一部份為延續先前實驗室學長之化合物，同樣以Benzimidazole為核心衍生物，將拉電子基團改為大小不同之推電子基團，比較推拉電子效應之差異性並應用於反式鈣鈦礦太陽能電池。由最後送測兩個分子之光物理性質及元件效率數據可知，推電子基團之YJS003在熱穩定性、電洞遷移率、光電轉換效率等數據表現皆優於拉電子基團之YJS001，因此，在此系列中以推電子基之表現較佳，目前YJS003最高光電轉換效率為15.76%，優於YJS001之11.30%。　　第二部分為研究合成Macrocyclic compound，有機環狀小分子應用於電洞傳輸材料無論是在太陽能電池亦或是有機發光二極體數量皆稀少，加上由先前環狀化合物之文獻相關報導指出，具D-A性質之環狀分子有利於孔柱狀之排列堆積，綜合以上因素，研究與設計一環狀分子，以TPA為Donor，Nitrobenzene group為Acceptor之D-A-D-A雜環化合物，分子合成尚在研究進行中。 ;The first part of this article continues the previous laboratory senior’s work. It also uses benzimidazole as the core, changing the electron-acceptor to the electron-donor group, comparing the difference of the electron-donor-acceptor effect and applying it to inverted perovskite solar cell. From the measurement of the photophysical properties and device efficiency data of YJS001 and YJS003, it can be seen that the YJS003 of the electron-donor group is better than the YJS001 of the electron-acceptor group in thermal stability, hole mobility, photoelectric conversion efficiency, etc. Therefore, in this YJS series, the performance of the electron-donor based is much better. At present, the highest power conversion efficiency of YJS003 is 15.76%, which is better than 11.30% of YJS001. 　　The second part is to design and synthesis macrocyclic compounds. Organic macrocyclic molecules are rarely used in hole transporting materials, whether in solar cells or organic light-emitting diodes. According to literature reports, macrocyclic molecules with D-A type are conducive to the arrangement of pore columns. Based on the above factors, research and design a cyclic molecule that use TPA as donor and nitrobenzene group as acceptor to synthesis D-A-D-A heterocyclic compound. Molecular synthesis is still in progress.
