摘要：

Self-assembly of ZnCl2 and the ligand 2,4,6-tris(4-pyridyl)pyridine (pytpy) in solution yields [(ZnCl2)(12)(pytpy)(8)](n) center dot xCHCl(3), a polycatenane consisting of a strand of mechanically interlocking icosahedral cages with an inner volume of more than 2700 angstrom(3). This can be used to encapsulate guest molecules of appropriate size and polarity, forming a precisely defined three-dimensional array of solvent nanodroplets within the crystalline framework. The dynamic composition of these droplets was studied using quantitative solid-state NMR spectroscopy.
