团簇是众所周知的具有原子精确结构的分子单元，其特点是具有亚纳米级的尺度和提供各种功能的迷人性质。使用溶剂操纵自组装的能力对于精确的纳米结构制造至关重要。在这里，我们报道了一种新的策略，通过脂质自组装的原理来制备多维(0−3)的纳米结构。首先，我们设计并合成了一个截断的锥形异族团簇Janus分子积木，它由两种类型的团簇组成，即。多金属氧酸盐(POM)和多面体低聚倍半硅氧烷(POSS)，它们通过有机连接物(OL)共价结合。通过调节溶剂的极性、氢键和分散力，得到了多种纳米结构。最后，我们探索了溶剂的溶解度参数与纳米结构之间的关系，为在不同溶剂中操纵的自组装纳米结构提供了系统的研究。这些有序的纳米结构可以作为一种理想的结构成分来填补无机晶体和纳米超晶之间的尺寸差距，这在下一代纳米器件的设计和开发中具有重要意义。
Clusters are well-known molecular units with atomically precise structures, which are characterized by their sub-nanometer scale and fascinating properties that offer a variety of functions. The ability to manipulate self-assembly using solvents is crucial for precise nanostructure fabrication. Herein, we report a novel strategy to fabricate nanostructures with multiple dimensions (0−3) via the principles of lipid self-assembly. First, we designed and synthesized a truncated cone heterocluster Janus molecular building block comprising two types of clusters, viz. polyoxometalate (POM) and polyhedral oligomeric silsesquioxane (POSS), which are covalently bound via an organic linker (OL). A variety of nanostructures was obtained by adjusting the solvent polarity, hydrogen bonding, and dispersion forces. Finally, we explored the relationship between the solubility parameter of solvents and nanostructures, providing a systematic study of self-assembled nanostructures manipulated in different solvents. These ordered nanostructures can serve as an ideal structural component to fill the gap in the size range between inorganic crystals and nanoparticle supracrystals, which is of significant importance in the design and development of next-generation nanodevices.
