Hybrid multi-porphyrin supramolecular assemblies: Synthesis and structure elucidation by 2D DOSY NMR studies

• Multi-porphyrin supramolecular assemblies on the base of Ru(II) and Sn(IV)-porphyrins were synthesized.
• 2D DOSY NMR spectra of the prepared supramolecular architectures were studied.
• Modern methods of two-dimentional NMR were adapted for the establishment of hybrid multi-porphyrin supramolecular assemblies structures and stability in solutions.

Design and synthesis of hybrid multi-metalloporphyrin assembles have been performed. The chemical structure of the synthesized complexes and their stability in solution were confirmed by the methods of 2D DOSY NMR spectroscopy, which have been specially adapted for these supramolecular architectures in solutions.
