Abstract
DNA binding of the ligand bearing an oxine and a pyridinium group was regulated by coexisting Cu2+ over the binding constant range of three orders of magnitude. The ligands coordinated to Cu2+ to form a dimer and then cooperatively bound outside of DNA duplex to give the well-regulated 1-D structure along the DNA backbone.
