Abstract:

The synthesis and characteristics of the naftalin-related macro-wheel ligants (E)-N-(naftalin-9-methylene)-2-(1,4,7,10-tetraazabiclo[8.2.2] tetradekan-4-il)-etanamine (4) and Cu(II), Ni (II), Zn (II) complexes have been made. Schiff obtained with some condensation reaction (E)-N-(naftalin-9-methylene)-2-bromoetanamine (2) molecule and glyoxal-bridge tetraase molecule with a reaction of monocater ammonium salt (3) was obtained. Then with a reduction reaction (E)-N-(naftalin-9-methylene)-2-(1,4,7,10-tetraazabiclo[8.2.2]tetradekan-4-il)-etanamine (4) macro-wheel ligant synthesis was completed. This macro-wheeled liganta, which is conformely limited to having a selective sensitivity to the transition metal ions, is connected to the fluorescence properties (14,7,10-tetraazacyclodekan) of naftalin. The floral characteristics of these macro-wheel ligants and complexes have been studied. According to the findings, this ligant is selectively characterized against the Zn(II) ions.

Abstract:

Synthesis and characterizations of naphthalene-bonded macrocyclic ligand (E)-N-(naphthalene-9-ylmethylene)-2-(1,4,7,10-tetraazabicyclo[8.2.2]tetradecan-4-yl)-ethanamine (4)and Cu(II), Ni (II), Zn (II) complexes were performed. By the reaction of (E)-N-(naphthalene-9-ylmethylene)-2-bromoethylamine (2), which was obtained by the Schiff base condensation reaction, and the glyoxal-bridged tetraaza molecule, the monoquaternary ammonium salt (3) was obtained. The synthesis of (E)-N-(naphthalene-9-ylmethylene)-2-(1,4,7,10-tetraazabicyclo[8.2.2]tetradecan-4-yl)-ethanamine (4) macrocyclic ligand was then completed by the reduction reaction. Fluorescence naphthalene group was bonded to this conformationally constrained macrocyclic ligand (1,4,7,10-tetraazacyclododecane) because of getting selectivity towards transition metal ions. The fluorescence properties of this macro cyclic ligand and its complexes were investigated. According to the results, it was found that this ligand was selective towards Zn (II) ions.
