Supramolecular assemblies based on sandwich phthalocyaninates are prominent components of functional optical and electronic materials. Previously1,2 we have synthesized heteroleptic yttrium triple-decker crownphthalocyaninates [(15C5)4Pc]Y(Pc)Y(Pc) – 1a and [(15C5)4Pc]Y[(15C5)4Pc]Y(Pc) – 2a and in the present work we have studied their supramolecular interaction with KOAc in CDCl3/CD3OD mixture by means of NMR-titration and diffusion ordered spectroscopy (DOSY). For complex 1a increasing of molecular volume by 2.39 upon interaction with KOAc was observed, suggesting the formation of dimer 1b. In the case of 2a the molecular volume is increased only by 1.43. Together with the results of NMR titration it suggests intercalation of K+ cations between crown-ligands with the formation of the complex 2b.
