摘要：
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.
