A flexible, pyridine-functionalized diaza-crown ether was self-assembled into discrete supramolecules of differing stoichiometries upon combination with various organoplatinum molecules. They are characterized by electrospray ionization mass spectrometry and (31)P[(1)H] and (1)H NMR. In one case, (1)H-(1)H NOE enhancements of a [1 + 1] assembled structure demonstrate the puckered shape of the macrocyclic ring. Despite its inherent flexibility, the dipyridyl-substituted 18-membered diaza-crown… Expand
