| Abstract: | A strategy is reported for the controlled assembly of organic‐inorganic heterostructures consisting of individual single‐walled carbon nanotubes (SWCNTs) selectively coupled to single semiconductor quantum dots (QDs). The assembly in aqueous solution was controlled towards the formation of monofunctionalized SWCNT‐QD structures. Photoluminescence studies in solution, and on surfaces at the single nanohybrid level, showed evidence of electronic coupling between the two nanostructures. The ability to covalently couple heterostructures with single particle control is crucial for the design of novel QD‐based optoelectronic and light‐energy conversion devices. |
