We report solution-based side-by-side self-assembly of Au-tipped CdSe nanorods (NRs) in large two-dimensional superlattices and the deposition of these lattices on a substrate with NRs aligned perpendicular to the surface. The side-by-side assembly of the NRs was triggered by changing the solvent quality for the ligands coating the long side of the nanorods. The stability of the self-assembled superlattices was enhanced due to the hydrogen bonding between the ligands attached to the Au tips of the nanorods. The reported approach can further facilitate the hierarchical integration of multicomponent NRs into functional devices.
我们报道了在大型二维超晶格中基于溶液的金尖端CdSe纳米棒（NRs）并排自组装，以及这些晶格在纳米棒垂直于表面排列的衬底上的沉积。纳米棒的并排组装是通过改变包覆纳米棒长边的配体的溶剂质量来触发的。由于附着在纳米棒金尖端的配体之间的氢键作用，自组装超晶格的稳定性得到了增强。所报道的方法可以进一步促进多组分纳米棒分级集成到功能器件中。
