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.
本文提出了一种用于单个单壁碳纳米管（SWCNT）末端的不对称化学功能化及其与不同单一组分选择性共轭的策略，即形成双功能化的R-CNT-R'异质结构。本研究通过在单个SWCNT的相对两端选择性地共价连接金属纳米颗粒（NP）和半导体纳米晶体（量子点，QD）来证明这一点；还进一步表征了杂化物不同组分之间的电子耦合。本研究开发的方法的普遍适用性可能有利于设计和开发具有单分子控制的新型基于SWCNT的纳米杂化材料。
