Popis: Europium monophthalocyanine Eu(acac)Pc, europium monotetranitrophthalocyanine Eu(acac)Pc(NO2)4, and heteroleptic europium tetranitrobisphthalocyanine Eu(Pc)(Pc(NO2)4) are synthesized. The spectral characteristics of the phthalocyanine complexes in the visible and near-infrared regions are studied. The photoluminescence spectra are recorded. The luminescence bands are detected in the regions 450–500 nm (S2 → S0) and 670–730 nm (S1 → S0). The peaks are attributed to electronic transitions in the organic ligands.
