摘要: 摘要
太阳能电池与内包分子碳簇化合物因能源应用性上的导引,此方面的研究已经吸引了很多科学家的兴趣。本论文以此研究方向为重点,利用二氮苯1c、2b、4c、6、7a–7g进行一系列于富勒烯上开了一个八圆环洞的反应。不过,于合成1c的过程中,我们发现所使用的□喃四氮苯与苯炔反应有选择性方面的问题。因此,本论文将先对□喃四氮苯做选择性方面的探讨。再者,具有八圆环洞的富勒烯化合物1–5,因其上官能基的不同,而于太阳能电池元件应用上各有不同的光电转换效率。其中,光电转换效率以化合物4与P3HT掺混后的1.07 %为最高;伴随着予体受体双缆聚合物于太阳能电池上的应用,我们尝试将溶解度好产率高的5f进行聚合反应。经由鉴定的结果发现,其确实有聚合物的生成,且可能因富勒烯易于接收电子的能力,使得此反应以一非常快的速率进行。
Abstract
Research of novel materials toward solar cell and hydrogen storage applications has been attracted considerable interests from many scientists in recent decades. This thesis presents research of synthetic work on novel fullerene derivatives incorporating chalcogenophenes. We use diazine 1c、2b、4c、6、7a–7g that undergo cycloadditions with fullerenes for the syntheses of a class of eight-membered-ring opening fullerenes. Initially, synthesis of diazene 1c was somewhat problematic due to the presence of dual reactive centers of its precursor with benzynes; hence, we study selectivity of furyl tetrazines with benzynes in chapter 2. In chapter 3, the prepared eight-membered-ring opening fullerenes 1–5 that gave photovoltaic power conversion efficiency ranging from 0.4% to 1.1% while fabricated with conducting polymer P3HT. The best photovoltaic power conversion efficiency is 1.07%, resulted from compound 4 blended with P3HT. Due to the interests for pursuing higher efficiency with donor-acceptor double cable polymers, we polymerized 5f oxidatively in short time that yielded insoluble materials.
