中文摘要:
      以超分子组装的方法实现三芳胺功能单元的长程有序排列,对于实现有机光电功能材料优异的导电性及空穴传输能力具有重要意义。该文合成一种新型三芳胺-均苯三甲酰胺基衍生物N1,N3,N5-三(3-((4-(双(4-(十二烷氧基)苯基)氨基)苯基)氨基)丙基)-1,3,5-苯三甲酰胺(H1)。通过紫外-可见吸收光谱及荧光光谱研究表明,H1在弱极性溶剂正庚烷中有较明显的自组装特性;分别用光学显微镜和扫描电子显微镜(SEM)观察了H1的自组装形貌;通过量子化学计算和电化学性质测试研究了H1的空穴传输性能,计算结果和实验测得的HOMO能级(-5.14 eV)、LUMO能级(-1.80 eV)均与钙钛矿能级匹配,同时测得H1的热分解温度为445°C。研究表明,H1具备作为空穴传输材料应用于钙钛矿太阳能电池的可能性。
英文摘要:
      To achieve excellent conductivity and hole transport capability of organic photoelectric functional materials, ordered long range arrangement of triarylamine functional units is achieved by using a su-pramolecular assembly method. A new compound N1,N3,N5-tris(3-((4-(bis(4-(dodecyloxy)phenyl)amino)phenyl)amino)propyl)benzene-1,3,5-trimethamide (H1) was thus synthesized. UV-Vis absorption and fluorescence spectra showed that H1 had self-assembly characteristics in the weak polar solvent n-heptane. The self-assembly morphology of H1 was observed by optical microscope and Scanning Electron Microscope (SEM), respectively. Further, quantum chemical calculations and electrochemical measurements were performed. The calculated results and measured HOMO level (-5.14 eV) and LUMO level (-1.80 eV) were matched with the energy levels of perovskite. The thermal decomposition temperature of H1 was found to be 445 °C. Thus, H1 could be potentially applied as a hole transport material in the perovskite solar cell.
