A N3O2-donor macrocycle bearing a naphathalic sulfonic group derived from 8,11,14-triaza-5,6: 16,17-dibenzo-1,4-dioxacycloheptadecane has been synthesized,and its structure was characterized by 1H NMR,MS data and elemental analysis。The interactions of the target compound with CT (calf thymus) DNA have been investigated by the ultraviolet spectrophotometry and fluorescence spectrophotometry。The results showed that the binding model between the N3O2-donor macrocycle and CT DNA was intercalation,with the binding constants being =20706.9 dm3•mol-1 and =12416.9 dm3•mol-1。The com-bination was the enthalpy driven reaction.
