Abstract
Complexes of ytterbium with various meso-tetrasubstituted porphyrins have been obtained and their spectral-luminescent properties have been investigated. It is shown that the quantum yield and the lifetime of 4f-luminescence of the ytterbium ion are higher in complexes with porphyrins that contain aromatic and heteroaromatic meso-substituents (as compared to n-alkyl ones) and also in complexes with the acetylacetonate ion as an extra-ligand.
