Size-Selective Supramolecular Chemistry in a Hydrocarbon Nanoring.

The article discusses a study that reveal that the supramolecular interactions in a hydrocarbon nanoring host, [6]paraphenyleneacetylene, have been shown with density functionals to be very strong and size-selective. The interaction strengths of two supramolecules where the guest molecules are fullerenes and of three supramolecules where guest molecules are truncated nanotubes have been calculated
