摘要: The novel tetrasubstituted metal-free phthalocyanine (4) and metallophthalocyanines (5, 6, 7 8) bearing four pyridyl group moieties on peripheral positions have been synthesized by cyclotetramerization of the phthalonitrile derivative (3) in a multi-step reaction sequence. new compounds were characterized combination elemental analysis, 1H- 13C-n.m.r., i.r., U.V.–vis m.s. spectral data.
