DNA has become very attractive as scaffold for functionalmolecules on the nanometre scale. We have shown that porphyrins attached to DNAform helical stacks of chromophores. In particular, a zipper-like construct hasshown to stabilise the DNA duplex, and for the first time the reversibleformation of photonic wires based on the DNA scaffold was demonstrated. Here wepresent new constructs of self-assembled nano-structures. Applications inelectron transfer, surface modification, DNA structure analysis and templatedformation of nanoparticle arrays will be discussed.
