values of both cationic tetrapyrazinoporphyrazines were measured and the singlet oxygen quantum (ΦΔ) yield value were measured by indirect method with DPBF (1,3-diphenylisobenzofuran) in DMSO. Both ΦF and ΦΔ of cationic zinc tetrapyrazinoporphyrazine derivatives exhibited reasonable values for photodynamictherapy application. The cationic zinc tetrapyrazinoporphyrazine derivatives substituted methylpyridinium

novel tetrapyrazinoporphyrazine-based fluorescent sensor for Cu2+ ion was synthesized and fully characterized by 1H NMR, MALDI-TOF MS, and elemental analysis. A tetrapyrazinoporphyrazine substituent was used as the reporting group and a 2,2′-dipyridylamine moiety was employed as the recognition group. The effects of various metal ions on the absorption and emission spectra of the designed molecule were

Tetrapyrazinoporphyrazine magnesium complexes were synthesized from 2,3-dicyano-5-(4-alkylphenyl)-6-(4-morpholinophenyl)pyrazine derivatives using freshly prepared solutions of magnesium butoxide in n-butanol. The corresponding metal-free derivatives were obtained by treatment with p-toluenesulfonic acid. Copper complexes were successfully synthesized using excess cuprous chloride and DBU (1,8-diazabicyclo[5,4,0]-7-undecene) as a catalyst in o-dichlorobenzene under reflux. The tetrapyrazinoporphyrazines were characterized by elemental analysis, UV-visible spectra, IR, MALDI-TOF Ms and H-1-NMR spectra.
