获得纳米尺度的有序结构对于纳米技术的发展是重要的。我们设计并合成了一系列含有一个六-正-六苯并晕苯（HBC）和两个多面体低聚倍半硅氧烷（POSS）结构单元的盘状立方体三单元体HBC-2 POSS。两个POSS单元通过酯键或酰胺键连接。在酰胺键的作用下，氢键的引入影响了HBC核的π-π相互作用和POSS单元的结晶相互作用之间的平衡。HBC-2 POSS三元组由于π-π相互作用、氢键和结晶相互作用等多种次级相互作用的协同作用而获得了分级有序结构。作为有机-无机杂化材料，这些HBC-2 POSS三元组是<10 nm模板的有希望的候选者。
Obtaining nanoscale-ordered structures is important for the development of nanotechnology. We designed and synthesized a series of disk-cube triads containing one hexa-peri-hexabenzocoronene (HBC) and two polyhedral oligomeric silsesquioxane (POSS) moieties, HBC–2POSS. The two POSS units were linked via ester or amide bonds. With the amide linkage used, the hydrogen bonding that was introduced affected the balance between the π–π interaction of HBC cores and crystallization interaction of POSS units. Hierarchically ordered structures were obtained from HBC–2POSS triads owing to the synergistic effect of multiple secondary interactions: π–π interaction, hydrogen bonding, and crystallization interaction. As organic–inorganic hybrid materials, these HBC–2POSS triads are promising candidates for templates <10 nm.
