Abstract

In the recent years the formation of nanocapsules that totally encapsulate guest compounds has attracted wide interest. In this work we demonstrate the formation of three-dimensional hydrogen bonded networks formed on self-assembly of tetradentate bis-pyrimidyl ligands with C-methylcalix[4]resorcinarene under a variety of different conditions. The single crystal X-ray crystallographic analysis revealed the formation of three different structural motifs. Two of the structures contain pairs of bowl-shaped resorcinarenes bridged by bis-pyrimidyl ligands in the formation of "chain-link" capsules capable of incorporating small guest molecules. The third structural motif has a bowl shaped resorcinarenes stacked in columns cross-linked by bridging bis-pyrimidyl ligands and water molecules. In this structure capsules are not formed.
