Palladium complex of octaphenyl-substituted pyrazinoporphyrazine: synthesis, photochemical and photophysical properties
Abstract
Novel palladium (II) tetrapyrazinoporphyrazinate, bearing eight peripheral phenyl groups, was obtained via metallation of the corresponding porphyrazine ligand. Target complex was identified using mass spectrometry, Fourier transform infrared and UV-Vis spectroscopy. Luminescence properties of palladium complex were investigated. Phosphorescence maximum of target compound was observed in the near IR region (828 nm). Singlet oxygen quantum yield (φ Δ ) was measured using the 1,3-diphenylisobenzofuran (DPBF) as the singlet oxygen trap. Value of ϕ Δ (0.35) is in a good agreement with literature data for porphyrazine complexes.
