Abstract:
The reaction of O2N2-donor naphthodiazacrown, with salicylaldehyde afforded new O3N2-donor macrocyclic ligands (L1-3naph) mounted with 1,3-diazcyclohexane subring in high yield. The product was characterized by IR, 1HNMR spectroscopy as well as elemental microanalysis and single crystal X-ray studies (just for L3naph). The interactions of [60]fullerene in presence and absence of base, Cu(II), Hg(II) and Zn(II) with L1-3naph were investigated employing fluorescence spectroscopy. The efficient fluorescence quenching of L1-3naph in presence of C60, Cu(II)( L1-2naph) and the fluorescence enhancement in presence of Hg(II) and Zn(II) indicated that the interaction with [60]fullerene Hg(II) and Zn(II),Cu(II) ( L3naph) were efficiently occurred. Meanwhile, the calculation of the association constants (K¬BH) employing Benesi-Hildebrand equation in CHCl3 showed a remarkable values for this interactions. The fluorescence data reveal that Hg(II) and Zn(II) make exo-coordination complexes with L1-3naph lingands
