The intramolecular hydrogen bonds in some Schiff bases derived from dendrimers: DAB-Am-8 and PAMAM-G2

The hydrogen bonding in some DAB-Am-8 and PAMAM-G2 dendrimer derivatives have been investigated by heteronuclear NMR techniques in solution. The proton positions in the bridges ware estimated on the base of nitrogen chemical shift of imine atom. Some dynamic effects connected with different segmental motion of particular parts of the molecules were found by analysis of spectral line widths.
