Click modification of diazido acridine intercalators: a versatile route towards decorated DNA nanostructures.

Diazido derivatives of 3,6-diamino acridine (proflavine) intercalate into DNA and undergo functionalization through click chemistry to form 1D nanostructures with redox active, conductive nanowire, and fluorescent properties. This two-step approach, intercalation followed by click modification allows for the controlled decoration of DNA nanostructures.
