Abstract
The novel tetrasubstituted metal-free phthalocyanine ( 6) and metallophthalocyanines ( 7, 8) bearing four 14-membered tetraaza macrocycles moieties on peripheral positions have been synthesized by cyclotetramerization reaction of phthalonitrile derivative ( 5) in a multi-step reaction sequence. The new compounds were characterized by a combination of IR, 1H NMR, 13C NMR, UV–vis, elemental analysis and MS spectral data.
