Abstract

The molecular weights and hydrodynamic radii of three different supramolecular assemblies formed by coordination of zinc-porphyrins with DABCO are estimated by means of ¹H NMR diffusion-ordered spectroscopy (DOSY) confirming their stoichiometries and sandwich-like structure already derived from ¹H NMR and UV/Vis titrations experiments.
