Özet

Metal-free and metallo-porphyrazines (M = Mg, 2H, Co, Cu, Zn, or ClFe) with eight (3-thiopropyl anthraquinone-2-carboxylate) units appending on the periphery through flexible alkylthio-bridges have been synthesized through esterification of octakis(hydroxypropylthio) porphyrazinato magnesium with anthraquinone-2-carboxylic acid in the presence of dicyclohexylcarbodiimide (DCCI) and toluene-p-sulfonic acid. The synthesized compounds were characterized by FT-IR, UV-vis, (1) H and C-13 NMR, mass spectrometry, and elemental analysis. Metal-free and several metallo-porphyrazines (M = Mg, 2H, Co, Cu, or Zn) carrying eight (3-thiopropyl anthraquinone-2-carboxylate) groups at the peripheral positions were synthesized from octakis(3-hydroxypropylthio) porphyrazinato] Mg(II). Symmetrically functionalized porphyrazines with eight ester units were soluble in common organic solvents. Chloro-octakis(3-thiopropyl anthraquinone-2-carboxylate) porphyrazinato iron(III) (FePzCl) was prepared by the reaction of metal-free porphyrazine with iron(II) acetate and further treatment with hydrochloric acid solution. The oligomeric structure [FePz(pyz)](n) and the monomeric compound [FePz(py)(2)] were formed as stable complexes by reacting FePzCl with pyrazine and pyridine, respectively. The porphyrazine compounds were characterized by different spectroscopic methods.
