The self-organizing and scaffolding properties of DNA are often used to assemble complex structures. We describe duplex DNA oligomers that contain a pyrene chromophore linked by a trimethylene chain to N4 of cytosine. Intercalation of the pyrene group stabilizes the duplex and causes efficient quenching of pyrene's fluorescence.
