A magnesium porphyrazinate carrying eight (9-anthracenyl) units on the periphery through flexible methylthio-bridges has been synthesized by cyclotetramerization of 3,4-(9-anthracenylmethylthio) pyrroline-2,5-diimine in the presence of magnesium butanolate. The metal-free derivative was obtained by treatment with trifluoroacetic acid and further reaction of this product with copper(II) acetate, zinc(II) acetate, and cobalt(II) acetate led to the metal porphyrazinates (M = Cu, Zn, Co). These novel compounds were characterized by elemental analysis, together with FT-IR, H-1-NMR, UV-Vis, and mass spectral data.
