Diffusion-based studies on the self-stacking and nanorod formation of platinum(II) intercalators.

Pulsed gradient spin-echo nuclear magnetic resonance diffusion measurements have been used to show that platinum(II)-based intercalating agents self-stack in solution and form nanorods 0.45-3.9 nm in length (at 25 mM); their lengths are dependent on metal complex concentration, salt concentration and solution temperature.
