✦ Synopsis

A series of chalcogen atom substituted porphyrazines have free macrocycles (4-9) were synthesized for all peripherally substituted porphyrazines. The unchalcogen-substituted Ni II , been assembled and characterized. Oxygen and sulfur chalcogen atoms have been substituted for peripheral

Cu II , and Zn II containing porphyrazine derivatives (10-12) were also synthesized because of the higher solubility of the methylene groups. Heteroatom-enriched, seven-membered ring dinitriles (1-3) were synthesized and characterized by metal-free porphyrazine 7. The macrocycles were characterized and studied using such techniques as UV-vis, IR, MS, UV-vis, 1 H NMR, elemental analysis, and X-ray analysis to examine the ring conformations. They were IR, elemental analysis, cyclic voltammetry, and electrical conductivity measurements. template cyclized in the presence of Mg II to form the Mg II containing porphyrazine macrocycles.
