Abstract
DNA-fibre ESR measurements reveal that the orientation of water-soluble cationic salen-type Schiff base complexes of copper(II) on DNA changes by modification of the bridging group between two imino nitrogens in the complex; the 1,2-phenylenediamine and 2,3-naphthalenediamine bridges enable the complex to intercalate to DNA, while the ethylenediamine bridge induces groove binding.Keywords
