2, four electron-withdrawing fluorine substituents at the periphery of the HBC core were introduced in HBCs 3 and 4. HBCs 2 and 4 have longer hydrophilic chains than those of HBCs 1 and 3. The self-assembly behaviors of amphiphilic HBCs 1–4 in different conditions were investigated, the results revealed that HBCs 1, 2 and 3 self-assembled into nanotubes, HBC 4 self-assembled into nanofibers.
四个不同的双子形六围-hexabenzocoronenes(负担沉重国家)1-4,携带
吡啶基所附侧链合成,和它们的自组装行为进行了研究。与HBC 1和2相比,在HBC 3和4中在HBC核的外围引入了四个吸电子的
氟取代基。HBC 2和4具有比HBC 1和3更长的亲
水链。研究了两亲HBC 1-4在不同条件下的自组装行为,结果表明HBC 1,2和3自组装为纳米管,HBC 4自组装为纳米纤维。
