Synthesis and characterization of pyridine ring chalco substituted new phthalocyanines

In the first step of this thesis, the heterocycle chalcone compound (2) bearing pyridine and hydroxyl group was obtained from the reaction of pyridine-3-aldehyde and 4'-hydroxyacetophenone. In the second step, the chalcone substituted phthalonitrile compound (3) was obtained by interacting with compound 2 and 4-nitrophthalonitrile compounds in DMF under argon atmosphere in K2CO3 medium. In the third step, the metal salts of 3 and Ni(Ac)2.4H2O, Co(Ac)2.4H2O, Zn(Ac)2.2H2O and Cu(Ac)2.2H2O metal salts were heated in DBU catalyzed argon atmosphere with heat gun. Thus, synthesis of new metal phthalocyanines was performed (4, 5, 6 and 7). The structure of the compounds 2 and 3 was characterized by 1H, 13C-NMR, FT-IR spectroscopy and the structure of the metal phthalocyanines obtained by UV-Vis, FT-IR and Mass spectroscopy.
