Abstract:
The dimensions and cavity sizes of the molecular capsules with the general formula [V10O18L4](10-) can be controlled modularly through the nature of the bifunctional, rigid organophosphonate ligands L(1) and L(2) (L(1) = bis(4-phosphonatophenyl)ethyne and L(2) = bis(4-phosphonatophenyl)butadiyne); the solution stability of the molecular entities as demonstrated by ESI-MS studies permits their assembly on the Au(111) surface on a sub-monolayer scale giving rise to a 2D supramolecular structure that is comparable to the packing arrangements of the capsules in the crystal structures.
