VI Vernadsky National Academy of Sciences of Ukraine popup.description2  Zirconium and hafnium phthalocyanines functionalized with aminobenzoic acids were synthesized, their composition and structure were established by NMR, IR spectroscopy and mass spectrometry methods, spectral-luminescent properties in DMSO and physiological solution were studied; the photoactivity of the studied complexes was proved by a test for the generation of singlet oxygen when irradiated with light in the range of the first biological window. A wide range of chromophore ligands based on dehydroacetic acid with substituents of different nature in the aromatic nucleus was obtained and their spectral properties were studied, their ability to complex formation was studied on the example of lanthanum complexes. A series of phthalocyanine complexes of zirconium and hafnium with extraplanar coordinated ligands-chromophores have been synthesized and characterized, and their spectral-luminescent properties have been studied. It is shown that the introduction of ligand complexes containing chromophore groups into the molecules leads to the appearance of additional absorption bands in the visible region of the spectrum, the dependence of spectral parameters on the chemical nature of ligands is analyzed.
