DNA nanotechnology provides one of the most interesting approaches to form tailored complex structures with precise control over molecular features. The ability of nucleic acid arrays to arrange other molecules allows potential applications in molecular-scale electronics. The nucleic acid nanostructures could provide a method for nanometer-scale control of the placement and overall architecture of these components, essentially using nucleic acid structures as a molecular breadboard. Coordination polymers may remarkable physical (luminescence, non-linear optics, magnetism and electrical conductivity) and chemical properties. Our approach tries to combine the molecular recognition capability of the DNA with the (multi)functional properties of certain coordination polymers as well as create artificial-DNA architectures using simple molecules and chemical reactions. We aim to form (multi)functional 1D and 2D coordination polymers containing nucleobases, and then connect those polymers to selected sequences of oligonucleotides to produce new nano-hybrid materials with new interesting properties and structural capabilities (including origami DNA). On the other hand we try to create architectures based on DNA by reaction of modified oligonucleotides with simple molecules.
