Interaction of polycationic Ni(II)-salophen complexes with G-quadruplex DNA
A series of nine Ni(II) salophen complexes involving one, two, or three alkyl-imidazolium side-chains was prepared. The lengths of the side-chains were varied from one to three carbons. The crystal structure of one complex revealed a square planar geometr
