Abstract
By considering previous experiments undertaken in our laboratory on OXNY (X=2,4 Y=2,3) azacrown complexes with [60]fullerene, it was found that factors such as the macroring size, type and number of the donor groups in these macrocyclic ligands had significant effects on their selectivity towards [60]fullerene complexation. In this research, 20 and 24-membered N2O4-azacrown macrocyclic ligands was synthesized and characterized applying 1H and 13C NMR spectroscopy, FT-IR as well as CHN elemental analysis. Interaction of these ligands with [60]fullerene and Cu(II) were monitored by UV-vis spectroscopy and applying Benesi-Hildebrand equation. The association constants (Ka) values related to the...
