Making Carbon Nanotube Rotaxanes
Single-walled carbon nanotubes (SWNTs) are a promising base for organic electronics, but attempts to add components to the structures to gain additional functions can change the material’s electronic properties by saturating desirable carbon-carbon double bonds. A team led by Emilio M. Pérez of Madrid Institute for Advanced Studies in Nanoscience, in Spain, has developed a strategy for tying a macrocycle around a SWNT, like a ring on a very long finger. . . .
