Length control of supramolecular polymeric nanofibers based on stacked planar platinum(ii) complexes by seeded-growth

The formation of high aspect ratio supramolecular polymeric nanofibers from square-planar platinum(II) complexes through Pt···Pt and π-π stacking interactions has been achieved with a small width (<15 nm), tunable length, and relatively narrow length distributions up to ca. 400 nm under conditions of kinetic control using small seed fibers as initiators.
