Abstract
Octa(2,6-difluorophenyl)tetraazaporphyrinate magnesium(II) has been treated with 96% sulfuric acid to obtain octa(2,6-difluorophenyl)tetraazaporphyrin. Coordination reactions of octa(2,6-difluorophenyl)tetraazaporphyrin and metal exchange of its magnesium complex with copper and nickel salts in dimethylformamide have been studied. Cu(II) and Ni(II) complexes with octa(2,6-difluorophenyl)tetraazaporphyrin have been synthesized. The resulting compounds have been identified by electron absorption, IR and 1H NMR spectroscopy, and mass spectrometry. The structures of the synthesized compounds were optimized by the DFT method. The fluorescence quantum yields of the studied compounds have been determined.
