Abstract: Europium monophthalocyanine Eu(acac)Pc, europium monotetranitrophthalocyanine Eu(acac)Pc(NO$_2$)$_4$, and heteroleptic europium tetranitrobisphthalocyanine Eu(Pc)(Pc(NO$_2$)$_4$) 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 $(S_2\to S_1)$ and 670–730 nm $(S_1\to S_0)$. The peaks are attributed to electronic transitions in the organic ligands.
