Pendant-arm macrocycles derived from the cyclocondensation reaction of sodium 2,6-diformyl-4-substitutedphenolates and tris-(2-aminoethyl)amine derivatives. Preparation, characterization and properties of their dinuclear copper(II) complexes

A series of pendant-arm Schiff base macrocycles have been obtained via the cyclocondensation reaction between sodium 2,6-diformyl-4-substitutedphenola tes and tris-(2-aminoethyl)- amine derivatives followed by transmetallation with Cu(ClO4)(2). 6H(2)O. The resulting dinuclear copper(II) complexes hav e been characterized by elemental analysis, infrared and mass spectra as we ll as magnetic moments at room temperature. All complexes have been electro chemically investigated, and two typical compounds have been studied with E SR spectra as well.
