In this work the synthesis, optical and luminescence spectroscopic characterization of the new ytterbium complexes with
asymmetric porphyrins of hematoporphyrin group, modified by two β-diketone fragments are presented. All ligands and
complexes are investigated by the methods of molecular mechanics, elemental analysis, UV-vis, IR, luminescence, mass
and 1H NMR spectroscopy. Influence of some factors (such as location of β-diketones substituents, value of charges on
ytterbium ion, etc.) on the value of 4f-luminescence is discussed.
