Abstract

The synthesis and characterization of two new ruthenium diporphyrazines is reported. The ruthenium (III) chloride in cyclotetramerization reaction with 5,6-diphenylpyrazine-2,3- dicarbonitrile or 1,2-dicyanobenzene resulted the green and blue diporphyrazinato counterparts respectively. The obtained diporphyrazines will to our knowledge be useful photosensitizers.

Keywords: Diphthalocyanine, porphyrazine, photocatalyst, photosensitizer, photodynamic therapy.
