Abstract

Mg(II)-octa-(3-fluorophenyl)tetraazaporphyrin and Zn(II)-octa-(3-fluorophenyl)tetraazaporphyrin were synthesized by boiling di-(3-fluorophenyl)maleic acid dinitrile with magnesium and zinc acetates in ethylene glycol. The corresponding Cu(II) and Mn(III)-porphyrazines were synthesized using the metal exchange reaction of the meta-fluoro-substituted magnesium complex with copper(II) and manganese(II) chlorides in dimethylformamide. The obtained compounds were identified by UV-Vis, 1H and 13 C NMR spectroscopy, mass spectrometry and elemental analysis methods. The fluorescence quantum yields of the studied complexes in tetrahydrofuran were determined. The photochemical stability of the synthesized complexes was studied.
