Naftalin-bağlı makro halkalı ligant (E)-N-(naftalin-9-ilmetilen)-2-(1,4,7,10-tetraazabisiklo[8.2.2] tetradekan-4-il)-etanamin (4) ve Cu(II), Ni (II), Zn (II) komplekslerinin sentez ve karakterizasyonları yapılmıştır. Schiff bazı kondenzasyon reaksiyonuyla elde edilen (E)-N-(naftalin-9-ilmetilen)-2-bromoetanamin (2) molekülü ve glioksal-köprülü tetraaza molekülünün reaksiyona tabi tutulmasıyla monokuaterner amonyum tuzu (3) elde edilmiştir. Daha sonra indirgenme reaksiyonu ile (E)-N-(naftalin-9-ilmetilen)-2-(1,4,7,10-tetraazabisiklo[8.2.2]tetradekan-4-il)-etanamin (4)makro halkalı ligantın sentezi tamamlanmıştır. Geçiş metal iyonlarına karşı seçici duyarlılığa sahip olması için konformasyonel olarak kısıtlandırılmış olan bu makro halkalı liganta (1,4,7,10-tetraazasiklododekan) floresans özellikteki naftalin bağlanmıştır. Bu makro halkalı ligantın ve komplekslerinin floresans özellikleri araştırılmıştır. Bulunan sonuçlara göre bu ligantın Zn(II) iyonlarına karşı seçici özellikte olduğu bulunmuştur.

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.
