Lanthanide Double-Decker Complexes with Tetra-tert-butyltetrabenzoporphyrin and Phthalocyanine Ligands. Synthesis and Properties

Mixed-ligand double-decker lutetium, erbium, dysprosium, gadolinium, and europium complexes with tetra-tert-butyltetrabenzoporphyrin and phthalocyanine have been synthesized, and their structure was confirmed by IR, 1H NMR, and mass spectra. Relations have been found between the electronic absorption and luminescence spectra of the complexes and radius of the central metal ion.
