“…The IR spectrum of the compound indicated the disappearance of the sharp C ≡ N stretching vibration after the conversion of (4) to MgPz, giving a significant absorption at 1628 cm −1 for C = N groups [34,35]. The 1 H and 13 C NMR spectra of MgPz in CDCl 3 confirmed the proposed structure.…”

The synthesis and characterization of a novel metal derivative of a peripherally symmetrically tetrasubstituted porphyrazine derived from 25, 26-dioxa-6,7,9,10,15,16,18,19-octahydro-25H-1,24-methanodibenzo[q,t][1,4, 13,16,17,10]tetraoxadithiacyclohenicosine-12,13-dicarbonitrile was carried out. The influence of metal cations such as Zn 2+ , Fe 2+ , Mn 2+ , Ni 2+ , Co 2+ , Hg 2+ and Cu 2+ on the spectroscopic properties of the ligands, the starting material dinitrile and MgPz were investigated in acetonitrile-chloroform solution (1/1) by means of absorption spectrometry. Absorption spectra showed isosbestic points in the spectrophotometric titration of Cu 2+ and Hg 2+ with MgPz ligand. The results of spectrophotometric titration experiments disclosed the complex stability constant of the novel ligand, MgPz with Cu 2+ and Hg 2+ cations.

“…The other step concerns demetalation of its magnesium porphyrazine to obtain metal-free derivative. The central, weakly-chelated magnesium ion was removed under in situ acidic condition such as acetic acid or trifluoroacetic acid [25]. The direct synthesis of the transition metal complexes of porphyrazine by cyclotetramerization of substituted maleonitrile in the presence of transition metal salts gives unsatisfactory results.…”

Novel octa-phenotiazine, octa-benzoazepine and octa-carbazole substituted magnesium(II) (MgPz-I-III) and zinc(II) (ZnPz-I-III) porphyrazines were synthesized from 2,3-bis [6-(4a,10a- (8) and 2,3-bis(6-carbazol-9-yl-hexylsulfanyl)-but-2-enedinitrile (10), respectively. These dinitrile derivatives 5, 8 and 10 were also prepared by the reaction of 1,2-dicyano-1,2-ethylenedithiolate di-sodium salt (4) with 10-(6-bromohexyl)-10H-phenothiazine (3), 5-(6-bromohexyl)-5H-diben-zo[b,f]azepine (7) and 9-(6-bromo-hexyl)-9H-carbazole (9), respectively. Porphyrazino-zinc(II) complexes were synthesized by one-step reaction using Zn(BuO) 2 as a template agent. All the novel compounds were characterized by elemental analysis and different spectroscopic methods such as 1 H NMR, 13 C NMR, FT-IR, UV-Vis and mass. The photochemical properties including photodegradation and singlet oxygen generation for magnesium(II) and zinc (II) porphyrazine complexes were studied in dimethylsulfoxide solutions for determination of their photosensitizer behaviors.
