超分子体系中次层相互作用对59Co NMR谱的影响

The Second Sphere Interaction in the Supramolecular Complexes Studiey by 59Co Solid Static NMR
Abstract:
59Co solid static NMR has demontrated that the hydrogen bonding interaction plays an important role in the supramolecular complexes formed by the [Co (CN)6]3- and protonated polyammonium macrocycles. The 59Co chemical shift spans Ω in the supramolecular complexes containing hydrogen boning interaction are considerably larger than that in K3[Co(CN)6] which bears the electronic static interaction only. Hydrogen bonding interaction changes the symmetry, of [Co(CN)6]3- in the supramolecules leading to the split of the triplex degenerate state 1T1g and the extent of the split reveals the extent of the hydrogen bonding. Accordingly, the changes of the aquation quantum yields in the supramolecules are alternatively rationalized.
