A molecular-scale interface, consisting of a “fused” heterojunction between a nanotube and a quantum dot, has been prepared. This work is significant for the construction of functional hierarchical assemblies with unique properties. The Figure shows a schematic representation of a CdTe quantum dot grown directly onto the oxygenated surface of an ozonized single-walled carbon nanotube template (see also inside cover).
