This research demonstrates single-molecule control of carbon nanotube heterostructures, suggesting new pathways for nanohybrid materials.
A strategy is presented for the asymmetric chemical functionalization of individual single‐walled carbon nanotubes (SWCNTs) termini and their selective conjugation to distinct single moieties, i.e., the formation of bi‐functionalized R‐CNT‐R’ heterostructures. This study demonstrates this via the selective covalent attachment of metal nanoparticles (NPs) and semiconductor nanocrystals (quantum dots, QDs) at opposite ends of individual SWCNTs; the electronic coupling is further characterized between the distinct components of the hybrids. The general applicability of the methodology developed by this study can be beneficial for the design and development of novel SWCNT‐based nanohybrid materials with single‐molecule control.
